Secret messages hidden in light-sensitive polymers
(PHYSorg.com Chemistry)

Scientists from the CNRS and Aix-Marseille Université have recently shown how valuable light-sensitive macromolecules are: When exposed to the right wavelength of light, they can be transformed so as to change, erase or decode the molecular message that they contain. The results of this research were published on Sept. 4, 2019, in Nature Communications.
