Russian biologists from Perm State National Research University developed a test system for the diagnosis of prostate cancer using carbon nanoparticles, RIA News reports with reference to the Ministry of Science and Higher Education of Russia.
On the surface of the carbon particles, there are recognition elements that can form bonds with the target. The analysis allows the recognition of a prostate-specific antigen, the large amount of which indicates the possibility of prostate cancer. Experts noted that the principle of the new analysis is similar to a pregnancy test: the test strip is placed in the test sample, and with a positive result, two coloured dots or stripes appear, while with a negative result appears only one. Currently, scientists are working on speeding up the test stripes production and improvement the accuracy of the results.
