摘要：
Control of a biological function was accomplished based on the manipulation of the absolute quantum yield of retinal photo-isomerization in bacteriorhodopsin under weak excitation conditions where only 1 from similar to 300 molecules absorbs a photon during an excitation cycle. Using tailored excitation light pulses found in optimization experiments we are able to manipulate the isomerization. yield by nearly 50% (both enhancement and suppression by similar to 23%) while keeping the number of absorbed photons constant.
