摘要：
Blue light, green light: High-speed atomic force microscopy visualized light-induced structural changes of the D96N bacteriorhodopsin (bR) mutant under alternate two-color illumination. With green light, each bR molecule is displaced outward from the trimer center. This activated structure is driven back to the ground state by the subsequent blue-light illumination (see picture).
