"using high-energy geometry that would not be possible at thermodynamic equilibrium, by administering light to aqueous solution... behavior at root of many functions in living organisms... eco-friendly sunlight... interlocking components: cyclodextrins, hollow water-soluble truncated cone shaped molecules, and azobenzene derivatives, molecules changing shape under light... self-assembly/ photochemical reaction harnesses light, accumulating unstable products, paving way for nanomotors, smart drugs"
