25 Sep Integrated microfluidic platform for real-time neural probing and wireless drug delivery
Drug delivery systems aim at the controlled release and targeted delivery of pharmaceutical compounds to the body. With the advances made in miniaturized devices and microfluidic flow control systems, we are steps closer to fully automated microfluidic drug delivery systems with real-time monitoring capabilities. For this week’s research highlight, we have selected one such advancement. In this article published in Nature Communication, a research group integrated a PDMS-based microfluidic device with wireless neural prob for real-time investigation of the effects of the drug on mice.
“Herein, we present a miniaturized, wireless neural probe system with the capability of delivering drugs for the real-time investigation of the effects of the drugs on both behavioral and neural activities in socially interacting mice. We demonstrate wireless drug delivery and simultaneous monitoring of the resulting neural, behavioral changes, as well as the dose-dependent and repeatable responses to drugs. Furthermore, in pairs of mice, we use a food competition assay in which social interaction was modulated by the delivery of the drug, and the resulting changes in their neural activities are analyzed.“, the authors explained.
“We expect that our system will be utilized as an effective tool for the screening of neurological drugs and that it will contribute to the development of pharmacotherapy for various neurological disorders.“, the authors concluded.
