Abstract

The TOPSi/HAP composite was obtained after heat treatment of thermally oxidized porous silicon (TOPSi) spin coated with Hydroxyapatite (HAP) precursor solution. Silicon-Calcium Phosphate composite nanoparticles (SiCaPs) were synthesized in distilled water by laser ablation method using the TOPSi/HAP composite as the target material. According to Scanning Electron Microscopy (SEM), Fourier Transformed Infrared spectroscopy (FTIR), Energy-dispersive X-ray Spectroscopy (EDS), Dynamic Light Scattering (DLS) and Zeta Potential analyzes, SiCAPs are ultra-pure, spherical shaped nanoparticles with an average hydrodynamic diameter of 120 nm and a Zeta Potential of-20 mV for Ph 4,5. The proposed unique method enabled the SiCaPs synthesis. By changing some parameters of the synthesis conditions, SiCaPs of various properties can be designed for bone tissue engineering, wound healing, drug delivery, medical adhesives, and various biomedical applications.
