Prof. Kazuo Umemura

Tokyo University of Science, Japan

Dr. Kazuo Umemura is a full professor of Tokyo University of Science. His specialty is biophysics, especially, nanobioscience and nanobiotechnology. One of his recent interests is nanoscopic research of hybrids of biomolecules and carbon nanotubes (CNTs). Unique structures and physical/chemical properties of the hybrids are promising in biological applications such as nanobiosensors and drug delivery. Dr. Umemura received his B.S. degree in Physics from Nagoya University. His M.S. and Ph.D. degrees were given from Tokyo Institute of Technology. After working at several institutes/universities as a researcher in Japan and in China, he became a professor of Tokyo University of Science. Kagurazaka campus of Tokyo University of Science is located at the center of Tokyo, so five subway/railway lines reach in front of the campus

"Nanobiosensing Using Optical Responses of Carbon Nanotubes"

Abstract: Nanocarbons such as carbon nanotube and graphene are promising nanomaterials for various nanoscopic applications including biological and medical applications. Several research groups proposed new methods of detecting DNA mismatch using nanocarbons. Drug delivery systems using nanocarbons were also reported by several authors. In this talk, we demonstrated evaluation of antioxidant ability of catechin using DNA wrapped carbon nanotubes. Catechin is one of the major components of teas. Because near-infrared absorbance and near-infrared photoluminescence of carbon nanotubes are sensitively changed by oxidation and reduction, the antioxidant ability of catechin were well monitored as functions of times and concentrations. Furthermore, we focused on effects of chirality of carbon nanotubes on the nanobiosensing applications.

"From Environmental Wastes to High-Value Aerogels for Engineering Applications"

Abstract: This talk will focus on how to reuse the environmental waste to solve environmental problems. The paper waste, fabric waste and plastic bottle waste can be converted into advanced eco-friendly aerogels for several applications such as oil spill cleaning, sound and thermal insulation, fire-retardant and CO2 filtering and medical devices. More facile, cost effective, much less time-consuming fabrication methods have been innovated. The continuous and large-scale process takes much less time and uses much less non-toxic chemicals than previous aerogel techniques. Water-repellent structures of the carbon-based aerogels are stable over 6 months in tropical climate. They can absorb oil excluding water 4 times larger than that of the best commercial sorbents. The aerogels can be squeezed to recover over 99% of absorbed crude oil and then reused several times. Thermal jackets using the carbon-based aerogels can maintain ice slurry inside water bottles for up to 4 hours. The compressed aerogels in the pallet form can be effective to be used to haemorrhage control within 5 seconds. With a simple but effective surface coating method, the aerogels can absorb large amount of CO2 from air and stand up to 620oC.
