Moleculair slot


Onderzoekers aan het Weizmann Instituut in Israel zijn erin geslaagd een soort moleculair digitaal slot te maken:
"By harnessing the principles of molecular Boolean logic, we have designed a molecular device that mimics the operation of an electronic keypad lock [...] The different password entries are coded by a combination of two chemical and one optical input signals, which can activate, separately, blue or green fluorescence output channels from pyrene or fluorescein fluorophores. The information in each channel is a single-bit light output signal that can be used to authorize a user, to verify authentication of a product, or to initiate a higher process. [...]"
