查询词典 silver

According to the characteristic of silver nanoparticles, their uniform dispersion in reaction media was obtained by surface modification, ultrasonic radiation and the select of emulsion, and then emulsion polymerization system were formed by combination with reactive monomer and initiator. Nano-Ag/Polystyrene core-shell particles were prepared by emulsion polymerization and their microstructure were characterized by TEM, FTIR, XPS, AFM and TG/DTA. The experimental results showed that silver nanoparticles were coated by polymer and the composite particles had typical core/shell structure, and the microlevel combination was realized. Meantime, the form mechanism of nano-Ag/polystyrene core-shell particles was tentatively researched. The conclusion is that the perfect coating was able to obtained by the control of reaction condition.

Coli. Transmission electron microscopy was used to evaluate the cell morphology of both the normal and the treated E. coli. The observation with TEM suggested that silver nanoparticles lead to the formation of "pits" in cell wall of the bacteria, and silver nanoparticles could enter into periplasm through the pits and destroyed the cell membrane.

采用透射电镜观察了经纳米银粒子处理过的大肠杆菌细胞形态变化过程，结果显示纳米银粒子先在细胞壁上产生小的孔洞，通过这些孔洞进入周质空间，导致细胞膜成分渗漏和破坏细胞膜，进而进入细胞内部。
