Abstract

original image

A free-standing polysaccharide nanosheet prepared by using a spin-coating-assisted layer-by-layer method is transferred from silicone rubber onto human skin (see figure) by fabricating a three-layered ‘nano-adhesive plaster' involving a water-soluble sacrificial layer. By using this novel technique, conventional ultrathin films can be made without the need for a solid substrate.
