Abstract

Emulating the ECM microenvironment of natural tissue and understanding how such an environment affects integrin function is a major goal of regenerative medicine and tissue engineering. In this work we have combined laser and aerosol techniques to create nanoengineered substrates comprising calcium phosphate nanoparticles of well controlled size on atomically flat SiO2 layers. In our process, gas suspended calcium phosphate nanoparticles are generated by ablation of a solid hydroxyapatite target inside a tube furnace at 800-900°C in presence of argon/H2O flow using a KrF excimer laser and deposited on a silicon substrate via electrostatic precipitation. Measurements reveal that our system is capable of synthesizing size selected calcium phosphate nanoparticles and the substrates created exhibit some physical characteristics that are similar to those found in the ECM of bone tissue.
