Abstract
The challenge of treating neurological disorders has motivated the development of implantable devices that can deliver treatment when and where it’s needed. This study presents a novel brain implant capable of electrophoretically delivering drugs and recording local neural activity on the surface of the brain. The drug delivery is made possible by the integration of a microfluidic ion pump (µFIP) into a conformable electrocorticography (ECoG) device with recording cites embedded next to the drug delivery outlets. The µFIP ECoG device can deliver a high capacity of several biologically important cationic species on demand. The therapeutic potential of the device is demonstrated by using it to deliver neurotransmitters in a rodent model while simultaneously recording local neural activity. These developments represent a significant step forward for cortical drug-delivery systems.

The current recommendation prototype on the Apollo Repository will be turned off on 03 February 2023. Although the pilot has been fruitful for both parties, the service provider IKVA is focusing on horizon scanning products and so the recommender service can no longer be supported. We recognise the importance of recommender services in supporting research discovery and are evaluating offerings from other service providers.
