Organization of hydrophilic nanoparticles on a hydrogel surface and their gel-assisted transfer to solid substrates
Two-dimensional organization of water-soluble nanoparticles, by using a hydrogel (agarose gel) surface as a substrate, is described here. The nanoparticles can be subsequently transferred onto various solid surfaces, a process promoted by the agarose acting as a "molecular glue". The Figure shows silica nanoparticles transferred to a highly oriented pyrolytic graphite surface.
