In this thesis, we did modifications of alkyl groups upon benzyl fluorophosphonate. In order to study the influence of alkyl length and steric effect on activity and selectivity of probes, we synthesized benzyl fluorophosphonate recognition heads with modifications including ethyl, butyl, octyl and cyclohexyl. By way of connecting different kinds of tag like azido group, biotin and rhodamine with recognition heads separately through a higher hydrophilic ethylene glycol derived linker, a series of benzyl fluorophosphonate probes were made up. And they will apply to various biological testing strategies.

在本论文中，我们以苯甲基氟化磷酸酯为基础，於其上进行一系列烷基之修饰，为了探讨烷基长度与空间立体性质对於探针活性及选择性的影响，我们合成了包含乙烷基、丁烷基、辛烷基以及环己烷基修饰的苯甲基氟化磷酸酯辨识端，并藉由具较高亲水性的聚乙二醇衍生连接桥结合三种不同的发报端，分别有叠氮基团、生物素及萤光基团来构成不同的化学探针组合，这一系列苯甲基氟化磷酸酯类化学探针将可被应用於不同的生物测试策略。

Based on a comparative study of two coating methods, with mycoplasm hyopneumoniae or its antibody, a highly sensitive and accurate enzyme linked immunosorbent assay method has been developed for direct determination of biotin in the transformed yeast cultural media.

With this SPR sensor, avidin of concentration of 0.5 nmol/L was examined and a nice response characteristic was obtained. The result indicates that this device could be widely employed for measuring biomolecules.

利用这种传感器，测量浓度为 0.55nmol/L的抗生物素，得到很好的响应特性，证明该装置可用于生物分子的检测。

Methods:(1) Dissoluble PGN and CpG DNA were immobilized onto the surface of biotin cuvette for establishing target. Another effective tracking approach was established by immobilizing Escherichia lipid A F583 onto the surface of Non-derivatised cuvett. The biosensor technology was applied to screen anti-inflammatory TCM targeting on three key molecules.(2) The active compositions were isolated by AB-8 macroreticular resin from lycium bark. After the activities of compositions were evaluated, the most effective compositions was confirmed. In vitro, the affinities of different concentrations composition E binding with PGN, CpG DNA and lipid A were measured separately. The effect of composition E on vigor of RAW264.7 cells were tested by MTT and CCK-8, and its inhibition on TNF-α, which was released from RAW264.7 cells induced by PGN, CpG DNA and LPS, was also tested by ELISA. In vivo, murine sepsis models were made by intravenously heat-killed E.coli and heat-killed S.aureus, then protection of composition E on mice sepsis model were observed.
