Figure 3.
Release of bacteria-bead (E. coli-bead) conjugates from the Au patterned substrates. (a–b) Fluorescence line intensity plots across Au patterned substrates treated with (a) imidiazole or (b) EDTA (shown in black) as compared to control substrates treated with PBS (shown in red in panels a and b). Also shown are released bacteria-bead conjugates observed in the supernatant solution after release via (c) imidazole or (d) EDTA. These conjugates appear as co-localized red (E. coli)-green (bead) spots. Scale bars in panels c and d are 5 μm long.
