a Penetration depth of various wavelengths of solar energy in animal tissue. b Energy diagram of the low-energy excitation-based triplet-sensitized photoswitching. c Electron exchange via Dexter energy transfer due to the endothermic triplet energy gap between photosensitizer and photoisomer. d Triplet-sensitized photoswitching of azobenzene in aqueous solution after excitation-based 730 or 850 nm LED and modulation of the cardiac functions of the frog tadpole. S = photosensitizer, P = photoisomer, e = electron.
