Abstract

A novel micropattern-assisted nanoassembly (μPAN) method to organize highly ordered nanocolloidal arrays onto a nonfouling polymeric surface is reported. A high-density array of polyethylene glycol (PEG) hydrogel microwells is first fabri-cated on glass substrates with the minimal feature resolution of 1 μm using photo-lithography method. By simply controlling the colloidal concentration of the dip-ping solution, various well organized nanocolloidal patterns are assembled inside the PEG microwells. The novel μPAN method allows organizing highly ordered nano-colloidal arrays in a predictable and robust fashion, and may have future applications in photonic crystal fabrication, biological sensing, analytical detection and nano-assembly.
