Production of active lysozyme films by matrix assisted pulsed laser evaporation at 355Â nm

Thin lysozyme films have been produced in a dry environment by MAPLE (matrix assisted pulsed laser evaporation) from a water ice matrix irradiated by laser light at 355 nm above the absorption threshold of the protein. The film deposition rate for 1 wt% lysozyme shows a clear maximum at a moderate fluence of 2 J/cm2.
