Laser Deposited Calcium Phosphate Films, as Sublayers for Biomimetics Growth of Biocompatible Coatings

Room temperature pulse laser deposition (PLD) technique has been used to fabricate thin calcium phosphate layers on polymer to promote the subsequent biomimetic hydroxyapatite (HA) coating growth. Calcium-magnesium HA coating with plate like crystallites were formed in simulated body fluid (SBF) on sublayers deposited from HA target at high laser fluence (9 J/cm exp 2 ). Proposed PLD precursors for biomimetics growth can be used for a wide range of implants materials and polymers in particular.
