ABSTRACT
Self assembly of ligand-covered gold nanoparticles from water colloid solution on silicon dioxide substrate, modified, and patterned by low energy electron beam, has been observed. High selective adhesion of Au-nanoparticles on hydrophobic regions of wettability patterning was discovered and has been explained within the framework of the classical thermodynamic theory of particle adhesion on a substrate immersed into the colloid solution. The Au-nanoparticles patterns were imaged using confocal microscopy. Our results indicate that the developed technique may be considered as high resolution and environmentally clean technology for nanoparticles adhesion for metal nanoelectrode deposition, development of biosensor arrays, and nanophotonic devices.
