Abstract
Silver-hydroxyapatite (AgHAP) nanocomposites were synthesized by a one-pot microwave irradiation method. AgHAP consisted of hydroxyapatite with a hexagonal structure and metallic silver (Ag0) with a cubic structure. The crystallinity of hydroxyapatite phase and UV radiation absorption capability of AgHAP improved with prolonged microwave irradiation times. The hydroxyapatite in AgHAP formed nanorods (50–100 nm), while Ag0 were nanoparticles (10–25 nm). The sunscreen containing AgHAP with a prolonged irradiation time of 60 cycles (AgHAP60) exhibited the highest sun protection factor (SPF) of 7.08 ± 0.85. The porphyrin protection factor (PPF) of the AgHAP samples was approximately 8.26 to 8.64. Furthermore, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of AgHAP were 25 mg/ml.
