Project 2: Development of Rapid, Miniaturized Biosensors

点击翻译按钮获取中文摘要

It is the goal of this project Biosensors, to apply new and emerging technologies to implement bioassays that our colleagues at Davis have developed, with improvements in speed and/or sensitivity compared to conventional methods. Several new schemes for detection will be tested, including a nanowell format for trapping and interrogating our non-bleaching nanoparticle labels for DNA and immune assays; a magnetic/luminescent nanoparticle format for DNA assays; and a nanostructured liquid core waveguide for enhancement of fluorescence detection. The targets will include the pyrethroid metabolite 3-PBA, emerging problem compounds such as TCC, TCS and PBDE, and genes for microbes that are used in bioremediation activities. A sensor for TCDD and related compounds will be developed based on AhR technology.
