Polyelectrolyte Negative Resist Patterns as Templates for the Electrostatic Assembly of Nanoparticles and Electroless Deposition of Metallic Films

摘要

Nano- and micropatterned surfaces show applications in a wide range of technologies including mierofluidic devices, microelectronics, biochips, and biosensors. The deposition or assembly of nanoparticlesanocrystals (NPs/NCs) on surfaces offers a simple and versatile way of controlling the electronic, magnetic, optical, and biological properties of these surfaces. Available techniques for patterning NPs on surfaces include electrostatic self-assembly, dewetting, molecular recognition, microcontact printing, dip-pen nanolithography, ink-jet printing, standard photolithography, ion- and electron-beam lithography (EBL), and scanning probe lithography of self-assembled monolayers (SAMs) followed by NP self assembly.
