The second part , a renewable piezoelectric immunosensor is developed for the antibody of schistosoma - japonicum ( sjab ) . after incubating 32 kd molecular antigens of schistosoma japonicum ( sjag ) on the qcm by applying the immobilization above , the nonspecific sites on the immunosensor are sealed by using bsa and nrs together . the immunosensor can detect the sjab with the linear range of 0 . 54 ~ 32 . 50 ug / ml 以感染兔血清为检测对象，采用聚电解质吸附固定法，将日本血吸虫分子抗原( siag32kd )固定于石英晶振表面，再以牛血清白蛋白( bsa )和正常兔血清( nrs )联合封闭晶振上非特异性活性位点，可在0 . 54 32 . 50ug ml范围内检测感染兔血清中日本血吸虫抗体。
Bsa is used as a model macromolecule drug and the in - vitro release rate of bsa from chitosan nano - particles are sustained . the experiment results show that chitosan nano - particles prepared could be used as carrier for the delivery of drugs . in the presence of magnetite nano - particles prepared in our experiment , chitosan particles warpped the magnetite nano - particles 并以牛血清白蛋白( bsa )为模型药物进行了载药实验并进行了附载效率和体外释药速度测试，结果表明通过离子凝胶反应制备的壳聚糖微球有很好的缓释效果，可用于药物载体。
Aminated and hydroxylated polysulfone membranes were prepared by amination and hydroxylation reaction , respectively . then bovine albumin ( bsa ) - fixed membranes were obtained by crossed - linking albumin into porous membrane with 1 , 1 ' - carbonyldiimidazole and bisoxirane reagents , respectively . a mathematical model for facilitated transport in asymmetric membranes with fixed site carriers was derived by assuming an instantaneous , microscopic concentraion fluctuation in the membrane 以氯甲基聚砜为基材，通过相转化法制备出具有底部贯通孔的非对称膜，通过胺化和羟基化反应，分别制得胺化聚砜膜和羟基化聚砜膜，再采用羰基二咪唑和双环氧烷两种活化试剂对其进行活化，将牛血清白蛋白固载在膜内，获得固定白蛋白促进传递膜。
Perturbations that could change the secondary structure of protein are introduced in this thesis . appling 2d correlation spectrum , peaks conformation and their assignments in the region of amide i and iii are completed to the bovine serum albumin in the phosphate buffer solution under alkaline ph - independent perturbation 以牛血清白蛋白为例，应用二维红外相关光谱技术，综合应用酰胺带和酰胺带信息，对碱性ph扰动下的牛血清白蛋白二级结构在红外光谱酰胺带和酰胺带中的信息进行了谱峰确认及归属指派。
