To visualize the protein coatings formed on substrates and along the inside wall of channel, a solution containing red QDs was carefully injected into the channel and incubated for 1 hour and thoroughly washed with deionized water to remove the loosely bound QDs. Photographs were taken under UV light (254 nm). The adsorption of QDs onto protein coatings was based on metal coordination chemistry between His-tags and Ni-NTA–decorated QDs. Coating images were captured using camera (Canon EOS-3), and 3D images were recorded using a confocal microscope. Data are presented in Figs. 2A and 4 (A, C, and D) and fig. S8B.
