Hydroxylapatite (<50 nm)

Hydroxylapatite (Hydroxyapatite) (<50 nm) is a natural form of calcium phosphate and is the main mineral component of bones and teeth. Hydroxylapatite (<50 nm) can stimulate the expression and secretion of collagen in primary human dermal fibroblasts. Hydroxylapatite (<50 nm) has good biocompatibility, bioactivity, and bone conductivity, making it suitable for targeted drug or nucleic acid delivery. Hydroxylapatite (<50 nm) can be used in research on osteoarthritis, gout, and atherosclerosis^[1][2]. In Vitro: Hydroxylapatite is suspended in 0.2 μm filtered purified water, sonicated and vortexed for 5 min and collected by centrifugation at 16,000 g for 1 min. The procedure was repeated five times to wash the Hydroxylapatite particles and a 40 mg/mL stock suspension was prepared in 0.1 M NaCl before administering to cells^[1].
