An international group of researchers at NUST MISIS and Clemson University has proposed a new method for producing gold nanoparticles based on synthesis under the influence of ultraviolet light, the press service of MISIS reported.
“The method excludes the use of aggressive chemical agents; the resulting nanoparticles are safe for the body and can be used for the diagnosis and treatment of cancer. Gold nanoparticles are used in the process of catalysis, in electronics, and solar cells, but they are most interesting for Biomedicine. Their important advantage is the combination of properties necessary for so-called bioimaging, that is, detailed diagnosis of the tumor and subsequent therapy,” the report says.
As agents for bioimaging, the Institute explained, gold nanoparticles are usually used in computed tomography. Tumor therapy using gold nanoparticles can be performed by so-called photothermal therapy when the particles first accumulate in the tumor, and then warm up under the influence of an external field and destroy cancer cells.
Meanwhile, existing methods for producing gold nanoparticles usually require the use of reasonably aggressive chemical agents, which makes their further use in Biomedicine difficult, or require several stages of synthesis, which increases the cost of production.
Currently, a group of scientists continues a series of laboratory experiments in the preclinical stage of research.
