Grain-making scientists carry drugs for cancer treatment

Scientists at the Moscow State University (MGU) and the German Photon Jena Institute have created micro-silicon nanoparticles that contain drugs , to penetrate and destroy cancer cells without making bodily injury to the patient.

Nanoparticles decompose quite quickly and after 2 weeks have completely disappeared.

Scientist Lyudmila Osminkina of MGU said conventional nanoparticles are also capable of bringing drugs to the place needed to treat cancer or other diseases, but after a few months, they will begin to hurt the liver, The patient's kidneys, lungs and brain are not self-excreted from the body. However, the MGU team and the German Photon Jena Institute used the Raman spectroscopy method to monitor the movement of nanoparticles through body tissues to detect rapidly eliminating nanoparticles more and almost no harm to the body.

Results of monitoring silicon nanoparticles moving in breast cancer cells showed that 9 hours after injection, nanoparticles began to decay quite quickly and after 2 weeks completely disappeared.

Thereby, the scientists concluded that the best method is to "pack " anti-cancer drugs and other drugs inside silicon nanoparticles made of silicon nanowires. This nanoparticle has enough energy to deliver drugs to tumors, and quickly decompose into silicic acid and some other molecules, without causing dangerous side effects as often happens with similar therapies.
