Abstract: Optical image sensors are 2D arrays of pixels that integrate semiconductor photodiodes and field effect transistors for efficient photon conversion and processing of generated electrons. With technological advancements and subsequent democratization of these sensors, opportunities for lens-less imaging and integration with microfluidics devices for biosensing applications are currently explored. 2D pixel arrays of such optical image sensors can reach dimensions larger than one centimeter with a sub-micrometer pixel size, allowing for high spatial resolution with large field of view. Integration of these sensors with microfluidics and sample handling offers new potential for biosensing at the point-of-care or point-of-need. In this presentation I will highlight technology advancements made in my lab, as well as applications.
