Integrating Microfluidics, Materials Science and Microbiology: Biosensors for Protecting Wastewater Treatment Systems

本研究的目的是探索细菌释放阳离子的现象及其传感器应用。接触化学毒素后，细菌会释放钾离子。这些离子反过来，当它们与聚合膜中的荧光团相互作用时，可以产生可检测的光信号。本项目将更详细地研究离子释放的生理和动力学。此外，将与美国国家标准与技术研究所化学科学与技术实验室合作开发一种集固定化细菌和光学传感于一体的毒性指示装置原型。这项拨款是根据招标NSF 00-49《环境新技术》获得的

0086883 Love The objective of this research is to explore the phenomenon and sensor applications of cation release from bacteria. Upon exposure to chemical toxins, bacteria release potassium ions. These ions, in turn, can generate a detectable optical signal when they interact with fluorophores that are incorporated into polymeric films. This project will investigate the physiology and kinetics of ion release in more detail. Additionally, a prototype toxic indicator device that integrates immobilized bacteria and optical sensing will be developed in collaboration with the Chemical Science and Technology Laboratory at the National Institute of Standards and Technology. This grant is made pursuant to Solicitation NSF 00-49, New Technologies for the Environment.***
