The goal of this project is to develop an integrated microsystem platform that can incorporate an array of bio-interfaces into a cost-effective, highly accurate, continuous-use, electrochemical characterization system suitable for a wide range of proteins. This device would provide revolutionary capabilities for protein characterization, including (1) simultaneous activity measurement for many soluble and membrane proteins, (2) rapid, automated interrogation using multiple electrochemical techniques, (3) microthermoregulation of individual protein sites, and (4) reduced costs per assay.

Novel bio-interfaces would provide new methods to measure activities of thermophilic proteins and develop protein-based technologies (e.g., biosensors). Molecular self-assembly of bio-interfaces would facilitate automated functionalization of the array. Embedded temperature control would allow a novel “cold sensing” technique that would prolong the lifetime of expensive proteins and reagents. A new, adaptive circuit topology would enable multiple electrochemical interrogation methods on a single chip, including an innovative method for rapid, low-frequency impedance spectroscopy.
