INTRODUCTION OF LABORATORY

Our research is based on organic chemistry, supramolecular chemistry, and interfacial science. We freely synthesize functional molecules that are often assembled at appropriate interface. For example, synthesized molecular machines are aligned as thin films on water surface, and these molecular machines are operated by hand-like motion of film compression and expansion to catch and release a target molecule. Such molecular machines and insect-like supramolecular assemblies are also transferred on highly sensitive mechanical sensors. Highly sensitive detection of environmentally toxic gasses and super-bio discrimination of amino acids and nucleic acid bases are actually accomplished. We aim to create functional molecular systems that no one have ever prepared.

Message

CAN WE CONTROL MOLECULAR MACHINES BY OUR HAND? BIG FINDINGS ARE ALWAYS HIDDEN BEHIND IMPOSSIBLE QUESTIONS

I want to be different from others, be storage guy, be in minority Group, behave unexpectedly, and work hard like superhuman (but I cannot probably be a smart professor). Last year, Nobel prize of chemistry was given to molecular machines that are operated upon sophisticated molecular designs and are currently by top-level nanotechnology. However, we are trying to operate molecular machines by our hands to make them for everyone's use. Crazy ideas, catch and release of a molecule by hands and nucleic acid base discrimination much better than DNA by hands, can be done with our secrete interfacial technique.
