In Siberia, nanodiamond developed for brain drug delivery

The scientists from the Novosibirsk-based Institute of Cytology and Genetics, Institute of Catalysis and International Tomography Center of the Siberian branch of the Russian Academy of Sciences (RAS) have discovered a new channel for the delivery of drugs into a patients brain, Siberian News Agency Novosibirsk reports, citing Alexander Aseyev, the chairman of the RAS Siberian branch.

Nanoparticles arrive at the brain using olfactory nerve fibers as transport. This has been experimentally proven and is now opening up new opportunities for overcoming barriers that typically get in the way of drugs, he explained.

At the heart of the technology is the nanodimensional diamond, to which three special enzymes are added; following an array of transformations, biochemical reactions produce a colored solution for drug delivery.

The system is operational in a broad range of temperatures and acidities and can show signs of activity after long storage at +4 degrees Celsius.

This is expected to make diagnostics easier and more reliable, Mr. Aseyev said.
