Magnetic nanomaterials coated with gold - black radiation, used in manufacturing cancer drugs
The study, conducted by the Center for Young Science and Technology Development of Ho Chi Minh City, shows that magnetic nanomaterials coated with gold - black radiation help improve the activity of black radiation, have potential in manufacturing drugs for cancer treatment.

Nanotechnology is increasingly being used in life. In particular, the use of nanomaterials in biomedical applications, such as increasing the sensitivity of diagnosis and targeted treatment, is being interested in research and development in the country and the world.

One of the nanomaterials with special properties and applications in medicine - biology is gold nanomaterials because of their high biological compatibility. To increase the application value of gold nanoparticles, it is often grafted with another material, such as a magnetic material.

Black radiation is a popular medicinal plant in Vietnam, with biological antioxidant activity, capable of destroying some malignant tumors. In order to improve the activity of black radiation, the authors researched to fabricate a gold-coated magnetic nanomaterial carrying drugs derived from black radiation, aiming to inhibit cancer cell proliferation.

Accordingly, the black thyme leaves are washed, dried, and then ground into powder. Then add water, boil to get extract. By the thermal decomposition method, the group synthesized Fe3O4 @ Au (gold-coated ferromagnetic nanoparticles), then added a black refractive agent, Fe3O4 @ Au material - black-radiation.

Research results show huge potential of new materials in the production of cancer drugs. The project was accepted by the Department of Science and Technology of Ho Chi Minh City in the past year. At present, the authors are continuing to cooperate with other research groups to promote experiments to evaluate and calibrate products from the sutudy, test on other types of cancer cells, in order to bring results of research in practice.
