Abstract:

Recently, in the transdermal drug delivery methods, the microneedle-mediated drug delivery system (DDS) has been developed to replace the hypodermic injection-mediated DDS, to provide painless self-administration of biological drug with patient friendly manner. Dissoluble microneedles are attracting many attentions as it has several advantages such as no needle-related risks. We have developed new fabrication methods for biodegradable microneedles array patches (MAPs), which are different with the conventional fabrication ones, such as stepwise casting method. Here, new transdermal drug delivery system by using dissoluble micro needle patch will be introduced. We also develop several aspects of bio-sensors components to accomplish portable Point-of-Care diagnostic devices, which are disposal, user-friendly, low-cost, and highly sensitive.

We fabricated porous microneedle on a paper substrate to develop a novel platform for direct integration of sensors. The device painlessly monitors fluid in the skin within seconds. Anyone can use the disposable patch without training, making it highly practical. Additionally, fabrication is easy, low cost, and the glucose sensor can be swapped for other paper-based sensors that monitor other important biomarkers.

Biography:

Beomjoon Kim is a Professor of Institute of Industrial Science, the University of Tokyo, Japan. Also, he is currently a director of LIMMS-KIKO, a director of CREMeB (Center for Research on Engineering in Medicine and Biology), and in charge as a chair of corporate sponsored research division of “Virological Medicine”, at I.I.S., the University of Tokyo. He received his B.E. degree from Seoul National University, Dept. of Mechanical Design and Production Eng., Korea, in 1993, and M.S., Ph.D. in Precision Engineering, from the University of Tokyo, Japan, in 1995 and 1998, respectively. He was a CNRS Associate Researcher in LPMO, Besancon, France (1998-99), and worked in MESA+ Research Institute, University of Twente (1999-2000).

He was an Associate Professor in the Univ. of Tokyo (2000-2013), and was a co-director at the CIRMM/CNRS Paris office (2001-2003). He investigates several aspects of bio-sensors components to accomplish portable Point-of-Care diagnostic devices, which are disposal, user-friendly, low-cost, and highly sensitive. Moreover, he is interested to develop self-powered, energy harvesting micro sensors as well as smart monitoring system. Recently, main research topic is focused to study on new transdermal drug delivery system by using dissoluble micro needle patch. He has published 113 peer reviewed journal papers, 216 international conference papers, 204 domestic conference papers as well as tens of patents, books publications so far.
