  45S5 Hench bio-glass (BG) has gained interest in research because of its
potential clinical applications. Several studies in-vivo and in-vitro have been
in progress to improve bio-integration efficiency of this glass. In present
contribution, surface modification of Hench BG has been done employing a
femtosecond (fs) laser beam, resulting in increased effective surface area of
the sample. These surface modified samples were subsequently immersed in
simulated body fluid for varying number of days and characterized using
Scanning electron microscope, energy dispersive X-ray analysis, X-ray
diffraction, and micro-Raman spectroscopy. In-vitro studies indicated superior
growth of hydroxyapatite (HAP) layer on the laser treated samples in comparison
to the untreated samples. Presence of strong XRD peaks confirmed faster growth
of HAP on laser treated samples. Raman peaks, five times more intense and
relatively narrower represented higher crystallinity of hydroxyapatite layer on
laser treated BG.
