反胶束法制备免疫脂质体

报道了反胶束法制备免疫质体的方法，先将水溶性包裹物（如药物等）包入反胶束中；在油／水界面膜上修饰有抗体，使反胶束穿过界面膜自动组装成免疫脂质体，负染电镜照片显示免疫脂质体为单层，直径在５０－４００ｎｍ范围，免疫脂质体溶解实验证明羊抗人ＩｇＧ已组装在脂质体上，该方法制备过程简单，包裹率、修饰率较高。     

PREPARATION OF STRIPE-SHAPED DOMAIN STRUCTURE IN FERROELECTRIC LIQUID CRYSTAL AND THE FABRICATION OF SPATIAL LIGHT MODULATOR

The stripe-shaped domain (SSD) structure was prepared in the initial ferroelectric liquid crystal (FLC) alignment without the application of an external electric field, which was realized by the aligning layer modification through the doping of tin tetra-2, 4-dimethyl phenoxy phthalocyanine (SnPc) into the rubbed polyimide films. Atomic force microscopy was used to investigate the alignment films and the corresponding aligning ability was evaluated through the pre-tilt angle measurement. The memory capability and the contrast ratio of thus aligned SSFLC cells have been enhanced and improved with the appearance of the SSD structure. The electrically controlled 64×64 FLC spatial light modulator was fabricated using the improved ligning method, which proves valuable for the practical device fabrication.     

自组装成膜技术制备TiO2薄膜的XPS研究

采用自组装成膜技术制备里TiO2薄膜,应用X射线光电子能谱研究自组装膜及其氧化膜和淀积的TiO2薄膜，结果表明，硅烷偶联剂成功地组装在玻璃基片上，足够长时间的氧化对使端基（-SH）完全氧化为磺酸基，淀积在基片上的TiO2膜牢固性好，平均膜厚在10nm．淀积膜中的钛可能有几种不同的氧化态，不同的酸度影响TiO2的淀积效果
