It is scattered in the two-dimentional titanium nanometer sheet and cell incubation of cell culture medium, two-dimentional a concentration of difference 0 of titanium nanometer sheet, 5,10,20,30,
50ppm, each experimental group set 3 parallel holes.After being incubated 2 hours, with the laser of 808nm, with 1W cm-2Power illumination 10
Minute, 24 hours after irradiation, with the vigor of CCK8 kit measurement cells.As shown in figure 12, the two-dimentional titanium of low concentration (5ppm)
The photo-thermal effect of nanometer sheet just has the cellkilling capacity of part, and under the conditions of 10ppm, highly significant is (right for killing ability
20% is can reach in cancer cell, 80%) macrophage can reach, in the concentration of more than 30ppm, the light of two-dimentional titanium nanometer sheet
Fuel factor can kill cell completely substantially.And PEG2000 claddings or uncoated two-dimentional its light of titanium nanometer sheet
Fuel factor killing ability is consistent.
Similarly, under conditions of 50ppm, the PEG2000 two-dimentional titanium nanometer sheets coated are incubated altogether with SMMC-7721 cells
It educates, then with 808nm, 1W cm-2Power irradiance, measure its killing under different light application times (0,2,5,8,10 minute)
Ability, as shown in figure 13, the only illumination of 2 minutes is just enough to kill all cells completely.
In conclusion the photo-thermal effect of two-dimentional titanium nanometer sheet can be used for cell killing, and low concentration, the short time it is near
With regard to good Cell killing efficacy can be reached under the conditions of infrared light, it is shown that its excellent photothermal conversion efficiency.
(4) the tumor thermal therapy effect measuring of two-dimentional titanium nanometer sheet photo-thermal effect
By 5 × 106SMMC-7721 cell subcutaneous injections are subcutaneous to female Balb/c nude mices, after about 10 days, tumour
Volume reaches 100-200mm3, using this liver cancer model as the object of two-dimentional titanium nanometer sheet photo-thermal therapy.By PEG2000 claddings
Two-dimentional titanium nanometer sheet is distributed in phosphate buffer, a concentration of 100ppm.During oncotherapy, 100 μ l nanometer sheets of intratumor injection
Dispersion liquid, then by mouse anesthesia, using the laser of 808 nano wave lengths, in 1Wcm-2Power under irradiation contain titanium nanometer sheet
Tumor locus 5 minutes, to carry out photo-thermal therapy to tumour.Figure 14 is to have recorded tumor locus temperature per minute with infrared detector
The situation of change of degree, Figure 15 are then the temperature variation curves of tumor locus in therapeutic process, the two captions are carrying out light
During heat cure, temperature raising is very quick caused by two-dimentional titanium nanometer sheet, and 20 DEG C can be increased in 1 minute.And at about 1 minute
Afterwards, temperature, which slowly rises, gradually keeps stablizing.Then, the 1st, 3,5,7,9,11,13,15 day after the treatment measures tumour respectively
Volume, as shown in figure 16, it is known that, tumor size reduces rapidly after photo-thermal therapy, the tumor group during entire treatment
It knits and is killed, tumour growth is inhibited, and achieves good therapeutic effect.
Therefore, the photo-thermal preparation comprising two-dimentional titanium nanometer sheet can be efficiently used for the photo-thermal therapy of tumour.
