EUROPEAN CONGRESS AND EXHIBITION ON ADVANCED MATERIALS AND PROCESSES - EUROMAT 2021

Atmospheric pressure plasma allows for the easy modification of materials surfaces for a wide range of technological applications. Coupling the aerosol injection of precursors with atmospheric pressure plasma largely extends the versatility of this kind of process; in fact solid and , in general, scarcely volatile precursors can be delivered to the plasma, extending the variety of chemical pathways to surface modification. Furthermore, labile bioactive molecule, that can be easily damaged in the reactive environment of plasma , when injected with aerosol are protected by a solvent shell. In this conditions, the deposition of drug containing coatings can be easily achieved, with application in the biomedical field as drug delivering systems, biosensing device and alike. Gentamicin, vancomycin and lysozyme containing films have been deposited preserving the antimicrobic activity. Such coatings show a release kinetic when immersed in water. Furthermore, it will be demonstrated that with a proper choice of aerosol solution and addition of ethylene as a source of the embedding matrix, unique core–shell nanocapsules can be obtained.
