We report the first successful deposition of fibrinogen blood protein thin films by matrix assisted pulsed laser evaporation using a KrF* excimer laser. We have demonstrate by Fourier transform infrared spectroscopy (FTIR) that our thin films are composed of fibrinogen and fibrin maintaining their chemical structures. FTIR spectra, atomic force microscopy (AFM) micrographs and fibrinogen concentration depend on the laser fluence. The best results

We report on the successful deposition of high quality type I fibrilar collagen thin films by Matrix assisted pulsed laser evaporation (MAPLE). Thin films deposition was performed in a N2 ambient (20 Pa) using a KrF* laser source (248 nm, 20 ns) operated at a repetition rate of 3 Hz, the incident laser energy at a value within the range (20-35) mJ, and the laser spot area was (3.5-18.5)±0.1mm2. The collagen films were deposited on double face polished

We report some results of a comparison between thin films of pullulan biopolymer obtained by pulsed laser deposition (PLD)and matrix-assisted pulsed laser evaporation (MAPLE). In experiments we used a KrF* laser source generating pulses of 248 nm and 20 ns pulse duration.W e demonstrate by Fourier transformed infrared spectroscopy (FTIR) that MAPLE is more appropriate than conventional PLD for transfer with high structural fidelity of biopolymers

Abstract Mussel adhesive proteins are a new class of biologically-derived materials that possess unique biocompatibility, bioactivity,and adhesion properties. We have demonstrated successful thin film growth of 3,4-dihydroxyphenyl-L-alanine modified poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (DOPA modified- PEO-PPO-PEO) block copolymer, a mussel adhesive protein analog, using matrix assisted pulsed laser evaporation. We have
