(a) Fluorescence image of a section of the CMOS microarray after addressing 39 combined layers of biotin NPs and GOx-avidin. (A) No current applied. (B) Current applied ONLY when biotin NPs were addressed. (C) Current applied when BOTH biotin NPs and GOx-avidin were addressed. (b) Corresponding MATLAB plot of the relative fluorescence intensity ( 𝑧 -axis) of each electrode.
