Vertically Aligned Peptide Nanostructures Using Plasma-Enhanced Chemical Vapor Deposition

`In this study, we utilize plasma-enhanced chemical vapor deposition (PECVD) for the deposition of nanostructures composed of diphenylalanine. PECVD is a solvent-free approach and allows sublimation of the peptide to form dense, uniform arrays of peptide nanostructures on a variety of substrates. The PECVD deposited D-diphenylalanine nanostructures have a range of chemical and physical properties depending On the specific discharge Parameters used during the deposition process.
