Thin Film Formation Of A Protein By Laser Ablation Deposition Technique

The ablation deposition technique was applied to a protein system for the first time. The sample polypeptide was silk fibroin with various excellent properties as a functional material. Chemical structures and surface morphology of thin films deposited by the technique were analyzed by infrared spectroscopy and atomic force microscopy, respectively. It is demonstrated that the ablation deposition is a powerful method to form a thin protein film.
