This technology could be used to actually manipulate DNA. Associate Professor of Physics, Samarendra Mohanty, states that macroscale applications are a possibility including "direct conversion of solar energy to mechanical energy" or even contemplating that it could possibly “simulate an environment in which photons radiated from the sun could propel the reflective motors in solar sails, a promising future technology for deep-space travel.” Link to Original Source
