Improved alternate deposition of biodegradable naturally occurring polymers onto a quartz crystal microbalance

Abstract

The ultrathin polymer films that were composed of biodegradable and naturally occurring chitosan and poly(γ-benzylglutamate) were stably deposited onto a quartz crystal microbalance (QCM) by alternate immersion of a QCM from their aqueous solutions in the presence of water-soluble organic solvents as a USS soluble solvent. © 1999 John Wiley & Sons, Inc.
