The protein envelop as well as the lipide membrane of HSV could be destroyed by surfactant, which destroys the DNA of HSV. Thus HSV loses the ability of infection. Sodium dodecyl sulfate is an anionic surfactant with biologic envelop denaturing potency.

HSV 的外部含脂质和蛋白质的包膜易为表面活性剂所破坏，引起胞膜通透性改变，使 HSV的 DNA 被破坏，从而失去感染能力。

SDS could dissolve the protein envelop as well as the lipide membrane of pathogen and cell. SDS is applied in light industry widely and safely, SDS is also made as microbicides in topical vaginal formulations to prevent the transmission of herpes and possibly other pathogens that cause sexually transmitted diseases,including HSV.

十二烷基硫酸钠(Sodium dodecyl sulfate，SDS)是一种阴离子型表面活性剂，为生物膜的最有效的溶解剂，它可以同病菌和各种高等动物的细胞膜的磷脂等脂质体结合而溶解，与蛋白质结合而变性。

Results are summarized as follows:(1) The absorption property of CdSe nanoparticle colloid under magnetic field was investigated by magnetic circular dichroism measurement, which proved the discrete energy states in CdSe nanoparticles due to size confinement effects.(2) Aggregation of small nanoparticles was usually observed under HRTEM measurements. In order to obtain HRTEM images of well dispersed particles, surfactant molecules were assembled on the surfaces of mercapto acetate stabilized CdSe nanoparticles.
