Bioactive properties of nanochitosan Bombyx mori

Nanochitosan with the size of particles in the range of 20–100 nm is synthesized from chitosan Bombyx mori. It is shown that preparations based on chitosan and nanochitosan are characterized by a well-pronounced antibacterial activity. Nanochitosan is able to substantially enhance the immune response of a living system: it increases the number of cells both in central (thymus, marrow) and peripheral (lymph glands) immune organs of mice.
