Figure 5

Stability and functionality of fNAP arrays deposited via microcontact printing. (a) Schematic illustration of fNAP microcontact printing. (b) SNRs of fNAP arrays before and after wash cycle. (c) Fluorescence images of fNAP arrays before and after testing. (d) (i) SNRs and (ii) CVs of fNAP arrays before and after testing. (e) Fluorescence images of fNAP arrays overlaid with target food products. (f) (i) SNRs and (ii) CVs of positive and negative state fNAP arrays when overlaid with target food. Error bars show standard deviation. Significance is indicated via ns/**** markers, corresponding to no significance and P < 0.0001, respectively. Scale bars show 50 ÎĽm.
