To achieve these goals, the technical solution adopted by the present invention is：A kind of carbon point as antineoplastic, prepare
Method comprises the following steps：Using arginine as carbon source, it is completely dissolved with water, adds appropriate ethylenediamine, ultrasonic dissolution, microwave adds
Heat produces target product carbon point.
A kind of above-mentioned carbon point as antineoplastic, described arginine are L arginine.
A kind of above-mentioned carbon point as antineoplastic, in molar ratio, ethylenediamine:Arginine=(1:2)-(1:4)；It is excellent
Choosing, ethylenediamine:Arginine=1:2.
A kind of above-mentioned carbon point as antineoplastic, microwave power 750W, heat time 4min.
Above-mentioned carbon point is alone or is blended in the application prepared in antineoplastic with other antineoplastics.
Carbon point prepared by the present invention with hydrogen peroxide effect in cancer cell by producing NO to kill cancer cell.Carbon point is
Using carbon atom as skeleton structure, size is less than 20nm, has the spherical nano particle of fluorescence property.The invention provides one
Kind can produce NO carbon point with hydroperoxidation, can be used as antineoplastic.The medicine be one not through transpassivation or
Modified carbon point.The fluorescent carbon point can be that it can give birth to the hydroperoxidation in cancer cell as the reason for treating cancer medicine
Into NO, and when the NO contents in cancer cell are higher than 1 μM with regard to that can play a part of killing cancer cell.In addition, the carbon point has
Fluorescence property can realize the diagnosis and treatment integration to cancer.
The beneficial effects of the invention are as follows：
1st, carbon point prepared by the present invention, particle diameter 1-5nm, and be equally distributed spherical particle, carbon point surface does not pass through
Transpassivation or modification, carbon point does not have toxicity, therefore can be used for biomedical sector, is made by itself and hydrogen peroxide in cancer cell
Can effective treating cancer with release NO.
2nd, the antineoplastic based on carbon point of the invention not only can with fluorescence imaging, but also with good biocompatibility,
The features such as NO burst sizes are more, effect circulation time is long, medicine stability is good.Such as in terms of bio-imaging：This fluorescent carbon point is made
With fluorescence imaging and then it can realize that the diagnosis and treatment of cancer are integrated in organism for antineoplastic.In addition, it can also pass through
Endocytosis, which enters cells play effect, makes its therapeutic effect more preferable；Its preparation method technique is simple, easily operated, prepares cost
It is low, it is easy to spread.
3rd, it is of the invention, arginine is made into carbon point, intracellular Fluorescence imaging can be realized and caused NO amounts are bigger, more
Be advantageous to its killing tumor cell.In addition, osmosis effect of the endocytosis of carbon point than arginine in biological cell in itself
Rate is higher, and this is also more conducive to the performance of drug effect.Carbon point prepared by the present invention can as antineoplastic in biomedicine should
With.
