This project plans to develop novel, sensitive, inexpensive and flexible electric biosensors to monitor potentially any molecule. It plans to use synthetic biology principles to develop a new class of artificial protein receptors that generate electric current upon encountering a molecular target. Using expertise in in vitro protein synthesis, the project plans to integrate biosensor design and electrode prototyping to achieve rapid development of low-cost broadly applicable sensory electrodes. To increase the sensitivity of the resulting sensing systems, the electrochemical receptors will be integrated with signal amplification cascades based on artificial autoinhibited proteases. The project aims to address the need for new technologies that enable collection of biological information outside of the laboratory environment.

该项目计划开发新型、灵敏、廉价和灵活的电生物传感器，以监测任何潜在的分子。它计划利用合成生物学原理开发一类新的人工蛋白质受体，这种受体在遇到分子靶点时会产生电流。利用体外蛋白质合成方面的专业知识，该项目计划将生物传感器设计和电极原型设计相结合，以快速开发低成本的广泛适用的传感电极。为了增加所得传感系统的灵敏度，电化学受体将与基于人工自抑制蛋白酶的信号放大级联集成。该项目旨在满足对新技术的需求，以便能够在实验室环境之外收集生物信息。
