Size-reduction of charge transfer area exploiting nTP and its application to nanoparticle placement. (A, B) KFM (Kelvin probe force microscopy [132]) images obtained from the e-μCP of metal-coated PDMS stamps without using nTP (A) and with using nTP (B). (C, D) SEM images of nanoparticle adsorption over the pattern of charge shown in (A) and (B), respectively. The nanoparticles are 200 nm sulfonate-modified PS spheres. The size-reduction pattern, (D), yields structures only one particle across. (Reprinted with permission from Reference [130]. Copyright 2005 Wiley-VCH.)
