This paper explores the use of photo patternable polymers for integrated high-speed screening arrays, where enzyme reactions are monitored in nano liter volume reactors using fluorescence of NADH and photodiode detection. Implementing the array of nano liter volume wells using a low-temperature CMOS-compatible process allows wells to be patterned after the photodiode array and electronics fabrication is completed. We demonstrate filling of 400 $MUL 400 micron square, 25 micron deep photoresist-on-silicon wells with liquid samples by electro spray and wetting. We also demonstrate usability of the wells on NADH samples by measuring the fluorescence of 0.1, 0.5 and 1 millimolar NADH solutions using external optics.@en
