Unbreakable Codes in Electrospun Fibers: Digitally Encoded Polymers to Stop Medicine Counterfeiting

Fluorescent polymer solutions can easily be electrospun into micrometer-sized fibers and subsequently encoded with long lasting digital codes by a photobleaching process. Such encoded fibers may find various applications; as illustrated in this report, placing encoded fibers in drug tablets may become a strategy to protect them from counterfeiting.
