Abstract
We have developed a soft lithography-based process to create microscale patterns of silica on a diverse array of substrates. A sacrificial polymer layer was first patterned using a micromolding technique. A peptide was adsorbed on the substrate and the sacrificial layer was removed. The patterned peptide template then catalyzed the deposition of silica from a silicic acid solution. With this procedure, we have created both continuous and discontinuous silica patterns on metallic, ceramic, and polymer substrates.
