Outline of Final Research Achievements

A single particle nanofabrication technique (SPNT) was successfully applied to the fabrication of reversible thermo-responsive and photo-responsive nano-actuators over a large area by using poly(N-isopropylacrylamide) and poly[(9,9’-di-n-octylfluorenyl-2,7-diyl)-co-4,4’-azobenzene]. Trapping of the polystyrene nano-particles by the thermo-responsive nano-actuators can be controlled by changing the temperature. Furthermore, the human serum albumin (HSA) nanowires of various lengths can be fabricated by SPNT. The biotinylated HSA nanowires can be transformed into nanowires exhibiting a biological function such as an enzyme through using avidin-biotin interaction. SPNT is expected to provide nano-actuators with sensor, which are otherwise difficult.
