RBP1 bioactive glass-ceramic films obtained by Pulsed Laser Deposition

• Thin glass ceramic bioactive films have been obtained by Pulsed Laser Deposition.
• Surface roughness can be varied in a controlled way by varying the deposition conditions.
• Films deposited at 600 °C have the same crystal structure of the target.

The deposition of thin films of bioactive materials is an issue of scientific and technological interest due to the possibility to combine mechanical strength of the implants and the bioactive properties of their surface. In this contest, we have deposited thin films of a bioactive glass-ceramics target of innovative composition by using the Pulsed Laser Deposition (PLD) technique. The deposition mechanism and the obtained films have been fully characterized by microscopic and spectroscopic techniques. It has been showed that films produced by nanosecond PLD are formed by the coalescence of nanometric droplets and films surface roughness can be suitable for the cell adhesion.
