Figure 4

Visibility of contact-printed microarrays composed of fluorophore-labelled DNA oligonucleotides. (a) Fluorescence images of DNA microarrays deposited onto polyethylene food packaging. (b) SNR values of fluorescent DNA microarrays at baseline and with overlaid products. Each value consists of 30 data points. Error bars represent standard deviation. (c) Fluorescence images of DNA microarrays once overlaid with target food products. (d) Coefficient of variation of baseline DNA microarrays. Performance threshold identified with a dashed line. (e) Coefficient of variation of DNA microarrays overlaid on target food products. All scale bars depict 50 ÎĽm.
