Abstract
Phenylalanine [C~9~H~11~NO~2~] is one of the essential amino acids in humans. DLβphenylalanine was crystallized in silica gel under suitable pH conditions by reduction of solubility method. The grown crystals were characterized by density measurement and Xβray powder diffraction. Fourier transform infrared spectroscopy, and thermogravimetric analysis were also carried out.

A glass with a composition (in mole %) of: SiO 2 (70), CaO (26), and P 2 O 5 (4) was obtained using a sol-gel method. The in vitro bioactivity of the glass was assessed by determining the changes in surface morphology and composition after soaking in simulated body fluid (SBF) for periods of up to 1
