Site‐Selective Integration of Monolayer‐Protected Inorganic Nanoparticles onto Surface Monolayer Templates by a Solvent‐Induced Lift‐Off Process
Source abstract
Abstract
Site-selective integration of a nanoparticle assembly on a surface monolayer template was achieved by penetration of solvents followed by selective lift-off of nanoporous granular films. Either positive or negative patterns on the substrate could be fabricated by appropriate selection of solvents used for washing (see figure), thus providing an effective methodology for desirable integration of various monolayer-protected inorganic nanoparticles through simple solution-based processing.

27. The resolution of patterns also depends on other experimental conditions. Large amounts of gold nanoparticles in solution during processing gave thick granular films (e.g. a few tens of micrometers in thickness) on the substrate with patterned monolayer templates. In this case when the obtained granular films were washed with water or chloroform patterns were generated but the edge of the remaining films was discontinuous. Therefore the concentration of gold nanoparticles in solution plays an important role for determining the resolution of the patterns and should be optimized to achieve high‐quality micropatterns depending on the feature size of the predesigned monolayer templates.
