Abstract
A method of fabricating a biopolymer array, and an apparatus which can execute the method, droplets of fluid carrying the biopolymer or a biomonomer are deposited onto a front side of a transparent substrate. Light is directed through the substrate from the front side, back through a substrate back side and a first set of deposited droplets on the first side to an image sensor. The substrate may be mounted by means of a chuck with parallel channels, and a scanning operation of a droplet dispensing head, light source, and sensor conducted in unison in the direction of the channels.
