Mixed-Signal VLSI Interface for High Aspect Ratio Optical/Electrochemical Hybrid Sensor Array

The main goal of the project is to design an integrated device that can make simultaneous electrochemical and optical measurements using a novel platform that combines high density micro-electrode array with optical fiber array for multiplexed analysis. The coupling of electrochemistry and spectroscopy increases the amount of information that can be obtained from a given sensor, preventing false positives and expanding the capabilities of a single mode sensing system. One of the main requirements for such a platform is the ability to perform individual interrogation of optical or electrochemical (or both types of) sensors in an array format with high throughput and reliability. The Catalyst Foundation will support the design of such a mixed signal VLSI interface to facilitate individual electrical/optical interrogation and readout. The integrated platform being created in this project will allow applications in the clinical, environmental, and chemical and bioprocess control areas.
