Selection and characteristics of peptides that bind thermally grown silicon dioxide films.

Dodecapeptides with affinity for thermally grown silicon dioxide were isolated by phage display. Selectants had high histidine content, though distributions of histidine are distinct from reported silica particle-precipitating peptides. Our peptides will have utility as nanoscale affinity domains when inserted into proteins intended for deposition on thermal oxide surfaces/interfaces in micro/nanodevices.
