Biomineral-binding ability of liposomes with the commercial synthetic HA (A) and the biotechnical HA (B). The commercial synthetic HA and the biotechnical HA were separately incubated with fluorescein sodium (a), fluor-NBL (b), BBL (c) and fluor-BBL (d). It was observed under an AMG microscope with an EVOS^® XL fluorescence microscopy illumination system (40×). The quantitative detection of binding ability (C, D) was conducted by detecting the binded icariin through HPLC method. All data are shown as means ± standard deviations (n = 3)
