Invited by Key Laboratory of Functional Crystals and Laser Technology, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences (TIPC, CAS), and China-Japan Joint Laboratory on Advanced Photonics,Prof. Eiichi TAMIYA from Osaka University visited TIPC, CAS and and gave an academic report on the class of the Progress inModern Chemistry on November 1, 2011. The title was Nano-biotechnology directed biosensor development: Nano-structured biosensing systems for medical diagnosis and analyzing cellular signals.

In the report, Prof. Eiichi TAMIYA introduced the nanostructured metals studied for the localized surface plasmon resonance (LSPR) and electrochemical biosensors. In his group, three types of nanostructures have been studied as biochip and the bio-sensing of these nanostructures have been examined by monitoring the biomolecular interactions in various flexible formats. Surface Enhanced Raman Scattering (SERS) was also discussed with gold and silver nanoparticles interacting with bio-molecules. Gold nanoparticles were successfully delivered into single cells. Spatiotemporal measurements of SERS fingerprints suggested the dynamic molecular interactions and transformations taking place at different locations with time in cardiomyocytes.

After the lecture, Prof. Eiichi TAMIYA visited Laboratory of Organic NanoPhotonics and had a further discussion. Prof. Eiichi TAMIYA's research interests are biochips and biosensors, nanotechnology based bioscience, bioengineering and micro-electro-mechanical systems (MEMS).
