Direct molecular patterning using a micro-stamp gel

摘要

A stamp for transferring molecules and molecular patterns to a substrate surface includes a backing and a polymeric gel bound to the backing and loaded with the a molecular species. Where the molecule to be patterned is a biomolecule, such as a protein or nucleic acid, the polymeric gel is typically a hydrogel. Exemplary hydrogels include sugar-based polyacrylates and polyacrylamides.
