Unbreakable codes in electrospun fibers: Digitally encoded polymers to stop medicine counterfeiting

Abstract

(Figure Presented) 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. © 2010 WILEY-VCH Verlag GmbH & Co.
