Fig. 2From: Synthesis and evaluation of nanosystem containing chondroitinase ABCI based on hydroxyapatiteFT-IR spectra of hydroxyapatite (HA) with and without immobilized chondroitinase; Comparison of the hydroxyapatite spectrum before and after enzyme immobilization shows changes in the peaks of the functional groups. The obtained FT-IR spectrum confirms the immobilization of the enzyme on the surface of the nanoparticlesBack to article page
