Research content introduction

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.

失敗してもいい、ドロップ・アウトしてもいい。世界的なハングリーさを持ち、常にチャレンジングであって欲しい。私たちは、分子を合成し、いろいろな形に集め、自由に操り、観察します。とてつもなく鋭敏で変幻自在に機能を変えることのセンサーの開発といった現実路線から、サイコロから触角が伸びていって昆虫のように鋭敏に物質を知覚する分子集合体のような、未知の物質開拓まで行っています。あなたの人生をあなたの研究にかけてみませんか?

Student voice

When I encounter questions and difficulties, I always visit office of Prof. Ariga. He always provides me useful suggestions and hints to solve the problems from his wide-ranged knowledge and experiences. However, sticking to old facts and ideas is not his preferable solutions. Free thinking and exceptional ideas are much more important for our research. Although he seams to be very busy, discussion with us is always his first priority. In our research group, we are trying to create functional molecules and novel materials by unprecedented methods and ideas. We have to be always thinking for new scientific challenges and are actually enjoying research life.

自分でアイデアを出し、本当にやる価値のある課題を定め、それを遂行した先に見える新しい発見は、何にも代えがたい喜びです。ぜひ有賀グループでそれを見つけてください。
