Flexible neural probe integrated microchannel and optical fiber for multifle stimulation

Recently, polymer-based neural probes are being extensively researched because of their potential to reduce neural damage during in vivo and in vitro insertion processes as compared to other types of neural probes. With the progress made in their fabrication processes, polymer probes with various functions, including electrical stimulation, drug delivery, and optical stimulation, are now as much in demand as silicon-based probes. In this study, we fabricated polymer neural probe, which is flexible and capable of simultaneously performing drug delivery, optical stimulation and electrical recording.
