The results of observation of different structuring techniques of thin m.tal layers applied in m.cro system.technologies are presented. The Ti V getter film. form.d by m.gnetron sputtering have been explored using scanning electron and atom.c-force m.croscopy, Brunauer-Em.ett-Teller m.thod, therm.gravim.tric analysis and fractal geom.try. The film.sorption capacity for hydrogen given by therm.gravim.try was of 7.7 m.·Pa·g-1. To estim.te the effective surface area, the fractal geom.try tools were used and the calculated value of the specific surface area was about 155 m./m.. The second object under investigation was a structure com.osed of m.cro- and m.soporous silicon and copper layer deposited electrochem.cally on the pore walls. Porous silicon when coupled with a reactive m.tal or alloy is expected to be an effective getter for m.cro system.techniques. The use of porous silicon and specific conditions of depositions allows to form.the structure of com.lex fractal type with a specific surface area of 167 m./cm..

以异硫氰酸荧光素(FITC)标记沙拉沙星合成荧光标记物,采用薄层色谱法提纯,优化了反应时间、标记物和抗体的工作浓度,建立了沙拉沙星的快速荧光偏振免疫分析法(FPIA)。本方法测定沙拉沙星在缓冲液中的半数抑制浓度(IC50)为43.2μg/L;检测范围为5.7～327μg/L,可以达到国家规定的动物性食品中兽药最高残留限量(80μg/kg)的要求。本研究考察了FPIA测定沙拉沙星的动力学过程及对其它4种喹诺酮类药物的交叉反应。结果表明,环丙沙星、恩诺沙星、加替沙星及氧氟沙星的交叉反应率分别为3.3%,1.8%,1.7%和0.7%。在牛奶和猪尿中沙拉沙星的回收率分别在71%～94%和74%～102%之间。本方法操作简单快捷,整个检测过程只需5 m.n、而且灵敏度较高、特异性强,适用于动物性食品中沙拉沙星残留的快速筛选检测。

A fluorescence polarization im.unoassay （FPIA） was developed for the analysis ofaflatoxins （AFs） using an anti-aflatoxin B1 （AFB1） m.noclonal antibody and a novel fluorescein-labeled AFB1 tracer. The FPIA showed an IC50 value of 23.33 ng/m. with a lim.t of detection of 13.12 ng/m. for AFB1. The cross-reactivities of AFB1, AFB2, AFG1, AFG2, AFm., and AFm. with the antibody were 100%, 65.7%, 143%, 23.5%, 111.4%, and 2%, respectively. The group-specificity of anti-AFB1m.b indicated that the FPIA could potentially be used in a screening m.thod for the detection of total AFs, albeit not AFG2 and AFm.. The total tim. required for analyzing 96 sam.les in one m.croplate was less than 5 rain. This study dem.nstrates the potential usefulness of the FPIA as a rapid and sim.le technique for m.nitoring AFs.
