Abstract:
1. A method for producing an ordered array of non-close packed colloidal 2D crystals on a substrate, comprising the steps: a) providing a suspension of microspheres comprising poly-N-isopropylamide (polyNIPAM), the microspheres being selected from pure poly-N-isopropylamide (polyNIPAM) hydrogel microspheres, functionalized polyNIPAM micro-spheres, and polymeric or inorganic beads carrying poly-N-isopropyl-amide (polyNIPAM) hydrogel chains, in an aqueous medium on a substrate, wherein the aqueous medium comprises a mixture of water and an alcohol, b) subjecting the suspension deposited on the substrate after step a) to a shear force generated by treating the suspension with a linear or pulsed gas stream, and c) drying the suspension.
