We present a hybrid nano-lithographic approach to minimizes the effects of line edge roughness and shot noise in nano-hole patterning by reflowing photoresist polymers around the nanoparticles deposited using self-assembly and simple etch chemistries. The method extends the transistor contact holes patterning limits to below 20 nm.

The sensitive optoelectronic properties of metal nanoparticles make nanoparticle-based materials a powerful tool to study fundamental biorecognition processes. Here we present a new and versatile method for coupling underivatized carbohydrates to gold nanoparticles (Au NPs) via the photochemically induced reaction of perfluorophenylazide (PFPA). A one-pot procedure was developed where Au NPs were synthesized and functionalized with PFPA by a ligand-exchange reaction. Carbohydrates were subsequently immobilized on the NPs by a fast light activation. The coupling reaction was efficient, resulting in high coupling yield as well as high ligand surface coverage. A colorimetric system based on the carbohydrate-modified Au NPs was …
