ABSTRACT
 
We report an efficient methodology for the self-assembled DNA-assisted assembly of the CoPt “core-shell” type nanoparticle (diameter: ~ 7 nm) between gold nanoelectrodes towards single electron transistor (SET).  It was confirmed that this methodology is selective and efficient one for the realization of SET through the study on the fixation of nanoparticle (diameter: ~ 10 nm) between nanoelectrodes by DNA (37 mer, 13 nm) and the measurement of  I – V characteristics with a Coulomb gap (~ 50 mV) in the device prepared by the DNA-assisted assembly of the CoPt nanocrystals between nanoelectrodes.
