We study primarily the antifouling ability of some microfilms and some biological activated substance , which provide some scientific basis for inventing the non - toxic antifouling coating 本实验对微生物粘膜和生物活性荐取物的防污性能作了初步探索,这对研制环保型的防污涂料提供了基础的科学依据。
Due to these inherent advantages , ecl method has attracted much attention from all analytical fields , especially from biochemical analysis . in this dissertation we focused on the preparation of a new type of dna probes which were labeled with ecl activated substances . based on coupling with the dna hybridization and immobilization techniques , we have developed new ecl methods for the determination of special dna sequence 本论文通过研究了多种ecl活性物质的发光性能,并以这些物质为标记物制备了多种高灵敏度的dna - ecl探针,结合dna杂交技术和dna固定化技术,将高灵敏度的ecl检测手段应用于生命物质dna的序列识别及含量测定,为dna传感器的研究和基因芯片的开发提供了新的思路和方法。
