Bioengineers and biophysicists from the National Research Nuclear University MEPhI, the Sechenov First Moscow State Medical University, the Universite de Reims Champagne-Ardenne in France, and the University of Tubingen in Germany have discovered that the toxicity of nanoparticles depends more on their size and the extent to which their surface area is charged than on their chemical composition.

"The problem of nanotoxicity became particularly relevant in connection with the prospects of using nanocrystals in medicine as an element for diagnostics and in therapeutic nanosystems," Igor Nabiev, study co-author and Professor at the University of Reims Champagne-Ardenne explained.

Problem - Toxicity - Nanocrystals - Increase - Nanotoxicity

"We have managed to solve the problem of controlling the toxicity of nanocrystals, which allows us to either increase or practically eliminate the nanotoxicity of particles of an extremely diverse nature, regardless of their chemical composition," the scientist added.

According to Professor...
