β-甲壳素/壳聚糖纳米级微粒的制备初步研究

Studies on Nano-crystal Particles of β-Chitin/Chitosan

采用物理和化学方法相结合的处理,制备了β 甲壳素/壳聚糖纳米级微粒.在这一制备过程中,预处理和反应的条件非常重要.从TEM照片看,这些纳米微晶颗粒的形状是圆形的,直径为10～100nm.

A kind of nanocrystal particles of βchitin/chitosan was prepared by both chemical and physical treatments. Preswelling and reaction condition were very important in this preparation. From TEM examination, the shape of these nanocrystal particles was spherical and their diameter was from 10～100 nm.
