AFM images show (A) the MUA-modified gold surface and (B) cyt <i>c</i> adsorbed on the MUA SAM at 450 sec.

Abstract

<p>Continuous AFM images of adsorbing cyt <i>c</i> molecules with real-time labels. Frame rate, 2 frames/s; image area, 150 × 150 nm². The cross sections of the images in (A) and (B), along the short white line, are shown in the lower right. </p
