Lasers, Optics & Photonics

Recent developments in nanomaterial synthesis and characterization have led to unprecedented material properties and device performance. On the other  and, many important applications see urgent needs for advanced material and device capabilities, and require large scale production of devices in order to make a real and significant impact. A big gap exists between the advanced  anotechnology and the macro scale applications. Here, I present a unique  aterial platform that aim to bridge the nano and macro worlds: multimaterial multifunctional fibers. I will introduce the scalable fabrication of multimaterial fibers via thermal drawing and the application of these flexible fiber devices in neural engineering, tissue engineering, drug delivery and optical sensing. In  articular, I will focus on the multimodality fibers for simultaneous optical,  lectrical and chemical interrogation of neural circuits in vivo and the  pplications of these fibers in a single-step optogenetic study. This technology will allow for more detailed manipulation and analysis of the neural network in deep brain regions of behaving animals than what current technologies achieved.
