Abstract
An imager may include an array of pixels formed on a substrate. A chemisorption layer such as a planar chemisorption layer may be deposited over the array of pixels. The chemisorption layer may include active sites that bond with anchoring molecules. The anchoring molecules may be bonded to the planar chemisorption layer in only localized regions each covering a respective pixel of the array of pixels. The image sensor may include a photoresist layer that covers the chemisorption layer. Openings in the photoresist layer may define the boundaries of the localized regions. The anchoring molecules may be bonded only with the chemisorption layer without bonding to the photoresist layer. The anchoring molecules may serve to bond with analyte molecules. By forming the anchoring molecules within only localized regions centered over respective pixels, spatial resolution of the imager when imaging the analyte molecules may be improved.
