Staining and Etching: A Simple Method to Fabricate Inorganic Nanostructures from Tissue Slices



original image

Staining and etching is developed for the fabrication of two-dimensional arrays and three-dimensional foam-like metallic nanostructures from a piece of tissue using a combination of metal staining and oxygen plasma etching. This novel nanofabrication technique is repeatable and cost effective, which are very attractive features from the perspective of nanomanufacturing process.
