2D optical imaging using photosystem I photosensor platform with 32x32 CMOS biosensor array

This paper presents 2D imaging using photosensor platform with a newly-proposed large-scale CMOS biosensor array in 0.6-μm standard CMOS. The platform combines photosystem I (PSI) isolated from Thermosynechococcus elongatus and a large-scale CMOS biosensor array. PSI converts the absorbed photons into electrons, which are then sensed by the CMOS biosensor array. The prototyped photosensor enables CMOS-based 2D imaging using PSI for the first time.
