HPSi nanoparticles were produced for the first time from heat treated porous silicon (HPSi) by pulsed laser
ablation in acetone and n-hexane liquids. Both HPSi nanoparticles and PSi (Porous silicon) and HPSi samples were
analyzed by various spectroscopic methods. From the Dynamic Light Scattering (DLS) analysis, it’s observed that the
highest size density of Si nanoparticles is 106nm and 80 nm which produced in acetone and n-hexane, respectively. We
produced silicone nanoparticles from heat treated porous silicone, which are characterized by strong Si-C bonds or strong
Si-O bonds with chemically tailored surfaces by laser ablation method. In addition, the HPSi nanoparticles are ultrapure,
blue luminescent and have spherical shapes as well as the desired zeta potential for biopolymer coating and other
biomedical applications. Heat treatment of porous silicone before short pulse laser ablation limits the size distribution
of the particles to a narrower range.
