Abstract

Integration of flexible electronics into nano-biomaterials is expected for medical diagnostics and therapeutics. Such devices should be conformable to physical and mechanical environment of a living body. In this regard, we have envisaged the development of free-standing polymeric ultra-thin films (referred to as “nanosheets”) for wearable and implantable devices. The polymer nanosheet shows tensto hundreds-of-nanometer thickness close to the scale of biomembranes, in which several polymers (e.g.,biodegradable polymers, conductive polymers, elastomers) can be formed into the ultra-thin structure by spincoating, layer-by-layer and gravure coating processes. The free-standing nanosheet showed flexible and adhesive properties derived from ultra-small flexural rigidity (< 10-2 nN m). In this talk, nanosheetbased devices (namely “printed nanofilms”) are introduced by combining nanosheet and printing technologies with variety of unique inks. The printed nanofilms allowed for directing cellular organization, monitoring biosignals or wirelessly delivering a light into tumors to perform photodynamic therapy.

About the Speaker

Dr. Fujie received his PhD (Engineering) in 2009 from Department of Life Science and Medical Bioscience, Graduate School of Advanced Science and Engineering, Waseda University. He spent postdoctoral periods at the Italian Institute of Technology (2010-12) and Tohoku University (2012-13). In 2013, he joined the Faculty of Science and Engineering, Waseda University as an Assistant Professor. In 2016, he moved to the Waseda Institute for Advanced Study (WIAS) and promoted to be an Associate Professor in 2018. He also served as a PRESTO researcher for the Japan Science and Technology Agency from 2015 to 2019. From November 2018, he moved to the current institute as a tenure-track faculty in the framework of Leading Initiative for Excellent Young Researchers (LEADER) by JSPS.
