This talk will be on the topics of DNA Nanotechnology research which have been carried out by Dr. Kawai's research group. Topics include:

(i) Ultra-high resolution "Scanning Probe Microscopy" imaging of single stranded and double stranded helix of DNA toward the Bio-nanotechnology.

(ii) Self-assembled two dimensional networks of DNA wires, nano-particle modification for nanoscale memories and DNA-FET devices toward DNA molecular electronics and DNA based electrochemical bio-sensors.
