Figure 2From: Two-stimuli manipulation of a biological motorManipulation of F 1 rotor motion by optical and chemical inputs. Sequential images of a rotating beads before and after a pulse (10 sec) of high intensity white light illumination (white bar) in the presence (A) or absence (B) of rhodamine 6G. (C) Rotating beads in the presence of rhodamine 6G, but without light pulse.Back to article page
