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.

纳米壳聚糖家蚕的生物活性

纳米壳聚糖是由壳聚糖Bombyx mori合成的，其粒径在20–100 nm范围内。结果表明，基于壳聚糖和纳米壳聚糖的制剂具有明显的抗菌活性。纳米壳聚糖能够显着增强生命系统的免疫反应：它可以增加小鼠中枢（胸腺，骨髓）和外周（淋巴腺）免疫器官的细胞数量。
