Description
Technical Field
The application belongs to the technical field of photo-thermal materials, and particularly relates to a composite photo-thermal material and a preparation method and application thereof.
Background
Cancer, also known as malignant tumor, has been a serious impact on human life and health. According to statistics, the number of new cancer cases rises from 1400 million per year to 2200 million per year by 2030, at present, 6 people are diagnosed as cancer every minute in China, 1 person in every 7-8 people die of cancer, and the cancer is becoming one of the most serious and harsh killers of human life and health. According to the latest tumor monitoring data published by the Shenzhen city chronic disease prevention and treatment center, 25587 new tumor cases of the resident population are reported in the Shenzhen city in 2018, wherein 11399 cases of men and 14188 cases of women have more number of women than men. Lung cancer remains localized to the whole and the first malignant tumor in men, and breast cancer remains localized to the first malignant tumor in women.
Currently, the methods for treating cancer are usually based on surgical treatment and chemotherapy. However, the conventional surgical treatment is difficult to completely remove the cancer tissues and cannot overcome the recurrence caused by the high metastasis of the malignant tumor. Although the chemotherapy can realize the whole body treatment, the administration efficiency of the current chemotherapy drugs is low, the toxic and side effects are large, and a large amount of normal body cells are killed while cancer cells are killed. In addition, the existing chemotherapy means is difficult to effectively track drug molecules and cannot judge the drug effect in real time, so that the accurate drug administration treatment of cancer cannot be realized. Therefore, the development of highly effective anticancer drugs with light-controlled release and precise administration has become a popular topic in the medical research field today.
Currently, photothermal therapy is receiving more and more attention as a novel tumor treatment method, and on one hand, the treatment characteristics of photothermal therapy enable a tumor region to form a high-temperature environment through near infrared light irradiation, so as to promote apoptosis of tumor cells; on the other hand, the controllable release of the drug at the tumor part can be promoted through high temperature, and the effects of precise drug delivery and synergistic promotion of killing of tumor cells are achieved. Wherein the two-dimensional materialThe material is widely used for the photothermal therapy of tumors due to good biocompatibility and higher photothermal conversion efficiency. For example, Huang Xiaohua at California university, san Francisco, regulates Ag in the growth liquid+A series of gold nanorods (AuNRs) with different sizes are synthesized in concentration, and the AuNRs with the best photothermal conversion efficiency are screened and used for photothermal therapy of metastatic cancer cells. The physical and chemical institute of the Chinese academy of sciences Geng Jianxin reports that the Graphene (GO) with functionalized surface is used as a photo-thermal agent to show enhanced photo-thermal effect in tumor treatment, and the enhancement mechanism is mainly that photo-generated energy is transferred from surface polymer molecules to the surface of the graphene so that the photo-thermal conversion efficiency reaches about 25%. The two-dimensional Black Phosphorus Quantum Dots (BPQDs) prepared by Zhang Han of Shenzhen university are used as photothermal agents for photothermal treatment of tumors, the photothermal conversion efficiency of the two-dimensional black phosphorus quantum dots reaches 28.4%, and the two-dimensional black phosphorus quantum dots show good biocompatibility. However, current two-dimensional materials such as gold nanorods and graphene still face the disadvantages of low photothermal conversion efficiency and poor stability as a photothermal agent. The search for a novel two-dimensional material photothermal agent with high photothermal conversion efficiency and high stability is still the key of the research on tumor photothermal therapy.
In addition, with the increasing improvement of pharmacology, pathology and diagnosis and treatment means, anticancer drugs with single function or treatment methods have not been able to meet the requirements of scientific research and application. Combination therapy is becoming a new strategy for current cancer treatment. Two or more anticancer drugs with different action mechanisms or treatment methods are effectively combined to play a synergistic effect so as to achieve the aim of better inhibiting the growth of tumors. Particularly, accurate administration of the nano composite medicine and efficient combined treatment of tumors through regulation and control of near infrared light have important research value and application prospect. Although the progress of combined treatment is reported in a public way at present, for example, the effect of doxorubicin (Dox) loaded on the carrier by the mesoporous silica-coated graphene oxide disclosed at present is better than that of a single-function anticancer drug on cytotoxicity, the current combined treatment drug has certain defects. The specific conditions include low photothermal conversion efficiency, and commonly used photothermal agents such as gold nanoshell (13%), gold nanorod (21%), graphene oxide (25%), and Cu2-xSe nanoparticles (22%), MoS2PEG nanosheets (27.6%), BPQD (28.4%), Bi2S3Nanorod (28.1%) or Bi2S3Nano spherical sponge (31.1%) and the like have low photothermal efficiency, so that the photothermal treatment effect is not ideal.

Therefore, the type of the surfactant and the amount of the surfactant bonded to the two-dimensional antimonene are the same as those of the surfactant and the modified bonding amount contained in the composite photothermal material. By modifying and combining the surfactant on the surface of the two-dimensional antimonene, the dispersity and the dispersion stability of the two-dimensional antimonene in the prepared dispersion liquid are improved, so that the uniformity of the loading of the nano silver particles in the step S02 can be improved.
In the embodiment, the method of surface modification of two-dimensional antimonene and combination of surfactant can be used for surface modification by mixing two-dimensional antimonene and surfactant in a solvent. Or in the process of preparing the two-dimensional antimonene, for example, in the process of preparing the two-dimensional antimonene by adopting an ultrasonic-assisted liquid phase stripping method, the two-dimensional antimonene is ultrasonically stripped by adopting a solution containing a surfactant, and the two-dimensional antimonene with the surface modified and combined with the surfactant is directly obtained.
In step S02, the silver nanoparticles formed on the two-dimensional stibene are silver nanoparticles 2 contained in the above composite photothermal material. Therefore, the relevant performance parameters, such as morphology and particle size, of the nano silver particles in step S02 are the same as the relevant performance parameters, etc., of the nano silver particles 2 contained in the above composite photo-thermal material. For the sake of brevity, the description of the nano-silver particles in step S02 is omitted.
In an embodiment, a method of forming nano-silver particles on two-dimensional antimonene includes the steps of:
s021: preparing two-dimensional antimonene modified by a surfactant into a two-dimensional antimonene dispersion liquid;
s022: adding silver salt and a reducing agent into the two-dimensional stibene dispersion liquid, carrying out mixing treatment and reduction reaction, and depositing nano silver particles on the two-dimensional stibene in situ;
wherein the surfactant and the two-dimensional antimonene in step S021 are the surfactant and the two-dimensional antimonene described above, respectively. The concentration of the two-dimensional antimonene dispersion liquid can be prepared and adjusted according to actual conditions, and the premise that the two-dimensional antimonene is fully dispersed is guaranteed.
The mixing ratio of the two-dimensional stibene dispersion liquid and the silver salt in the step S022 is to ensure that the grown nano silver particles meet the condition that the molar ratio of the two-dimensional stibene to the silver ions is 1: 0.05-1: 0.5. In embodiments, the silver salt is added as a silver complex, e.g., the complex should be any complex capable of forming a silver complex with a silver salt, such as but not limited to a silver ammine complexing solution. The silver salt is added in the form of silver complex, so that the morphology and size of the nano silver particles formed by deposition can be effectively controlled, for example, the nano silver particles formed by deposition are controlled to be in the sub-nano silver cluster morphology, and the particle size of the sub-nano silver cluster is further controlled to be 0.5 nm-100 nm.
In an embodiment, the reducing agent in step S022 includes at least one of sodium borohydride, hydrazine hydrate, aldehydes, hydrogen gas, and the like. The addition amount of the reducing agent should ensure that all silver ions are reduced to generate a silver simple substance to be precipitated, that is, the reducing agent should be excessive relative to the silver ions, for example, in the embodiment, the silver salt and the reducing agent are added and mixed according to the mass ratio of 100: 1-100: 20.
Further, the preparation method of the composite photo-thermal material according to the above embodiments further includes the following steps, as shown in step S03 in fig. 4:
the composite photo-thermal material is prepared into dispersion liquid, the dispersion liquid and the targeting agent are mixed, and the targeting agent is combined on the two-dimensional stibene and/or the nano silver particles.
In step S03, during the mixing process of the targeting agent and the composite photothermal material in step S02, the targeting agent adsorbs and binds to the two-dimensional antimonene and/or nano silver particles, such as a targeting agent coating layer can be formed, but not only, the coating layer can be continuous or discontinuous, and the amount of the targeting agent can be determined according to the actual amount of the adsorbed and bound targeting agent. Therefore, due to the existence of the targeting agent, the prepared composite photo-thermal material has accurate targeting on the basis of having the photo-thermal/photodynamic synergistic treatment effect.
In addition, the targeting agent in step S03 is targeting agent 3 contained in the above composite photothermal material. Therefore, the type, loading amount, etc. of the targeting agent in this step S03 are the same as those of the targeting agent 3 contained in the above composite photothermal material. For economy of disclosure, the description of the targeting agent in step S02 is omitted here. As in the embodiment, the mixing ratio of the dispersion liquid and the targeting agent ensures that the molar ratio of the two-dimensional stibene to the targeting agent is 1: 0.05-1: 0.2 on the prepared composite photo-thermal material. The target property of the composite photo-thermal material is improved by controlling and optimizing the load of the target agent on the composite photo-thermal material.
Therefore, the preparation method of the composite photo-thermal material in each embodiment can effectively prepare the composite photo-thermal material with the composite structure, and can control the particle size of the prepared composite photo-thermal material, the morphology, the particle size, the loading amount and the like of the nano silver-loaded particles by controlling the preparation conditions, so that the photo-thermal/photodynamic synergistic treatment effect of the prepared composite photo-thermal material is improved. Or further, the type of the targeting agent and the mixing ratio of the targeting agent and the two-dimensional stibene composite photo-thermal material loaded with the nano-silver particles are controlled, so that the load of the targeting agent on the prepared composite photo-thermal material is controlled, the precise targeting property of the composite photo-thermal material is endowed and improved, and different targeted precise dosing or photo-thermal treatment is realized and improved.
In a third aspect, embodiments of the present application provide applications of the above composite photothermal material. Based on the components contained in the composite photo-thermal material and the structure formed by the components in the embodiment of the application, the composite photo-thermal material has a photo-thermal/photodynamic cooperative treatment effect or further has accurate targeting, so that the application effect and the field of the composite photo-thermal material in the embodiment of the application are effectively enhanced.

The composite photo-thermal material provided by the embodiment of the application can also be used as a drug carrier of a certain active drug, so that accurate targeted drug delivery of the active drug is realized, and the synergistic treatment effect and effect of the active drug and photo-thermal and photodynamic therapy are realized. Of course, based on the structure and characteristics of the composite photo-thermal material in the embodiments of the present application, the composite photo-thermal material can also be applied to photo-thermal catalysis or photo-thermal power generation materials.

1. and (3) researching the photothermal effect based on stibene:
(1) photo-thermal performance experiment:
the two-dimensional antimonene distribution in examples 1 to 4 and comparative example 1 was prepared into aqueous dispersion solutions with different concentrations of 2 μ g/mL, 5 μ g/mL and 10 μ g/mL based on the mass of the two-dimensional antimonene, water was used as a blank test group (the concentration of the two-dimensional antimonene was 0 μ g/mL), 2mL of the aqueous dispersion solutions with different concentrations were added into a 32-well plate, then near-infrared laser irradiation was performed at 808nm, the temperature of the aqueous dispersion solution was recorded every 30 seconds, the laser irradiation was turned off after continuous recording for 30 minutes, the changes of the cooling temperature and time of the aqueous dispersion solution were recorded immediately, and finally, the change curve of the temperature change of the aqueous dispersion solution with the near-infrared irradiation time at different concentrations was obtained. The temperature change curve of the different aqueous dispersions of two-dimensional antimonylene in comparative example 1 with the irradiation time of near infrared light is shown as a in FIG. 6. As can be seen from the a diagram in figure 6, the two-dimensional antimonene has excellent photo-thermal performance. In addition, the temperature change curves of the aqueous dispersions of different composite photo-thermal materials of examples 1 to 4 with the irradiation time of near infrared light are substantially the same as the graph a in fig. 6. Therefore, the composite photo-thermal material disclosed by the embodiment of the application has a good photo-thermal effect, and the loaded sub-nano silver clusters and the targeting agent hardly influence the exertion of the photo-thermal property of the two-dimensional antimonene.
(2) Photothermal stability test:
and (3) after the photothermal performance test in the step (1) is finished, turning on the laser again for irradiation, repeating the irradiation for 3 to 5 times, and recording the temperature rise and temperature drop curves of the aqueous dispersion. Among them, the temperature change curve of the aqueous dispersion of the two-dimensional antimonene with the concentration of 5 mug/ml in the comparative example 1 along with the laser on and off is shown in the b diagram in fig. 6, and it can be seen from the b diagram in fig. 6 that the two-dimensional antimonene has excellent photo-thermal sensitivity and good photo-thermal effect stability. The temperature profile of the different aqueous dispersions of examples 1 to 4 with the laser switched on and off is substantially the same as that of graph b in fig. 6. Therefore, the composite photo-thermal material disclosed by the embodiment of the application has excellent photo-thermal sensitivity and good photo-thermal effect stability, and the loaded sub-nano silver clusters and the targeting agent hardly influence the performance of the photo-thermal performance of the two-dimensional antimonene.

Changes in ROS generated by dissociation of silver clusters were studied using 1, 3-Diphenylisobenzofuran (DPBF). The specific method comprises the following steps: and (3) fully mixing the prepared dispersion liquid with DPBF, irradiating by 808nm near-infrared laser, taking a quantitative solution every minute, centrifuging, measuring the UV-vis absorption spectrum of the filtrate, and researching the change curve of the ROS amount generated by silver cluster dissociation under the illumination condition. While a blank solution was used as a blank group. The curves of the ROS content of example 1, comparative example 1 and blank are shown in fig. 7. As can be seen from fig. 7, the amount of ROS generated by the dissociation of silver clusters in the light condition of the composite photothermal material provided in example 1 significantly increases with time, while the two-dimensional stibene and the blank group in comparative example 1 remain substantially unchanged, i.e., almost no ROS are generated in the light condition. In addition, the ROS amount generated by the dissociation of the silver clusters of the composite photo-thermal material provided by other examples under the illumination condition is the same as that of the ROS amount generated by the dissociation of the silver clusters in the illumination condition in the example 1, and the ROS amount is obviously increased along with the time.
3. The composite photo-thermal material is used for in vivo tumor treatment research.
The tumorigenic nude mice were randomly divided into 8 groups, treated in the following manner:
group 1: intravenous PBS;
group 2: injecting PBS intravenously and irradiating by 808nm laser;
group 3: injecting a PBS solution of antimonene (which is a composite photo-thermal material compared with the composite photo-thermal material in the embodiment 2 and does not contain silver clusters) with the surface modified with RGD polypeptide into a vein without irradiating the solution by near-infrared laser;
group 4: injecting a PBS solution of antimonene (which is a composite photo-thermal material compared with the composite photo-thermal material in the embodiment 2 and does not contain silver clusters) with the surface modified with RGD polypeptide into a vein, and irradiating the solution by using laser of 808 nm;
group 5: injecting a PBS solution of a silver cluster (relative to the composite photo-thermal material in the example 2, and without two-dimensional antimonene) with the surface modified with RGD polypeptide into a vein without irradiating the solution with near-infrared laser;
group 6: injecting PBS solution of silver clusters (compared with the composite photo-thermal material in the embodiment 2, and without two-dimensional stibene) with RGD polypeptides modified on the surface through vein, and irradiating by 808nm laser;
group 7: injecting PBS solution of silver cluster/stibene compound (composite photo-thermal material in example 2) with RGD polypeptide modified on the surface through vein without near infrared laser irradiation;
group 8: PBS solution of silver cluster/stibene compound (composite photo-thermal material of example 2) with RGD polypeptide surface modified is injected intravenously and irradiated by 808nm laser.
The dose, laser source and irradiation time were the same between groups, and were administered intravenously every 3 days for a total of 3-5 times. Tumor volume was measured every 3 days, mice were weighed every 3 days, and survival of mice was recorded every day until all PBS control mice died. One representative mouse per group was selected after one week of discontinuation of dosing, sacrificed and tumors were extirpated and their volume was measured to evaluate the status of tumor treatment. The results of the experiment are shown in table 1:
TABLE 1
As can be seen from the table 1, the group 8 is compared with the group 7, and the composite photo-thermal material can effectively play the role of photo-thermal/photodynamic cooperative therapy of the two-dimensional stibene and the silver clusters under the irradiation of the infrared laser, so that the tumor cells can be effectively killed. The killing effect is significantly higher for group 8 than for group 7.
Compared with the group 6 and the group 4, the group 8 shows that although the single silver cluster in the group 6 and the single stibene in the group 4 respectively have a certain effect of killing tumor cells under the irradiation of infrared laser, the group 6 and the group 4 have a remarkable effect of killing tumor cells lower than that of the group 8, so that the effect of effectively killing the tumor cells is effectively lower than that of the group 8, and therefore, the synergistic effect is effectively achieved between the stibene and the silver cluster in the composite photothermal material, the photothermal/photodynamic synergistic treatment effect is achieved, and the composite photothermal material is remarkably improved. The targeting agent loaded by the composite photo-thermal material can further realize accurate targeting drug delivery and release active drug components.
