Abstract
In a bioinspired approach, we are mimicking various types of naturally occurring materials to fabricate hybrid antibacterial and biocompatible thin films for a range of applications. In this work we will present a new process for generating the Chitin and Chitosan functionality using MLD. As precursors for this MLD process we are using the sugar-type molecules N-acetyl-D-mannosamine or N-acetyl-D-glucosamine and coupling them with the surface using thionyl chloride vapors. ATR-FTIR, X-ray photoelectron spectroscopy (XPS) and Solid-state NMR (ssNMR) analysis were used to characterize chitin-type MLD films grown at different temperatures from 70 to 125 ᵒC.
