■ 초록 

In neuroscience, optical neural stimulation method has become popular as it provides unique advantages over conventional electrical neural stimulation: remoteness, and the capability of inhibitory stimulation. Recently, photothermal stimulation based on light-induced localized heat generation (e.g. thermo-plasmonic effect) has been suggested as a promising optical neural stimulation without genetic modification. In order to apply the photothermal neural stimulation across multiple biological models, we must develop appropriate neural interfaces delivering the thermo-plasmonic characteristics.

In this talk, our recent efforts to develop the thermo-plasmonic neural interfaces for both in vitro and in vivo neuronal networks will be provided. A simple surface coating of neural interfaces using biocompatible polyelectrolyte and plasmonic gold nanoparticles can efficiently implement the thermo-plasmonic effects. Using the thermo-plasmonic effect, we fabricated multiple photothermal stimulation devices for both in vitro and in vivo, and we demonstrated optical neuromodulation at different scales.

Dr. Hongki Kang is currently an assistant professor in the Department of Information and Communication Engineering at DGIST (대구경북과학기술원). He received his MS and PhD in Electrical Engineering from the University of California, Berkeley in 2010 and 2013, respectively. Prior to joining DGIST, he spent several years as a postdoctoral researcher in the Department of Electrical Engineering at Columbia University and in the Department of Bio and Brain Engineering at KAIST. His current research is in the areas of flexible microelectronics, additive micro-manufacturing and neural engineering. With his interests in multidisciplinary research areas, he is interested in solving engineering problems at the intersection of electrical engineering and life sciences/biomedical engineering.
