The high cost and requirement of specialist facilities, has prevented the translation of continuous-flow microreactor technology to the industrial setting. Our researchers have developed an optically transparent continuous flow reactor, which is both cost effective and user friendly. The innovative method combines 3D printed moulds to generate channels in PDMS, which can then be sealed with a pressure sensitive adhesive tape. The microreactor has been applied to the production of both inorganic nanoparticles and organic liposomes, and performs well compared to existing reactor systems that are considerably more expensive and difficult to operate. We are currently working on creating novel pump-free reactors, for application in biotechnology and nanomedicine.
