Abstract

original image

Nanopattern fabrication of metal dots on a water-swollen hydrogel is performed by transcribing metallic nanodots from a solid substrate to the hydrogel surface. This fabrication technique may stimulate advances in nanoscience using soft, wet matter, enabling development of new ion-based bio-related devices. Au nano-dots on a hydrogel can produce iridescent color, and its spectral response can be finely modulated by controlling the nanodot spacing, as reported by Yoshihito Osada and co-workers on page 5243.
