Similar to the case of the bacteriorhodopsin, RC also accomplishes a photocycle-accompanying tunable lifetimes and wavelength ranges of absorption and refractive index changes from sub-ps to s time scales [20, 69] (Figure 6).
Using this type of cryo-EM, we analyzed the structure of bacteriorhodopsin, which was analyzed for the first time by Henderson and Unwin, pioneers in electron crystallography, (17) together with the loop regions and lipid molecules at a resolution of 3.0 [Angstrom].

Their topics include templating photoreactions in solutions, supramolecular photochirogenesis, the photochromism of multicomponent diarylethene crystals, controlling photoreactions through non-covalent interactions within zeolite nanocages, and protein-controlled ultrafast photoisomerization in rhodopsin and bacteriorhodopsin.
In another innovative approach, artificially prepared vesicles known as liposomes were assembled on a quartz crystal microbalance via layer-by-layer growth using the membrane protein bacteriorhodopsin as a binding reagent.
For instance, light-activated excitation of rhodopsin (bacteriorhodopsin) molecules, involved in the hyperpolarization process of the cell membrane, can either generate nerve impulses, ATP synthesis, or regulate embryogenesis [1-5].
