A Heating performance of AuMu nanostructures synthesized at pH 3, 6, and 9 (PGM concentration of 8 mg/ml) under irradiation with an 808 nm NIR laser at 1.25 W/cm2. B–C Bacterial growth following irradiation of the MRSA-infected TS broth with the NIR laser for 0, 1, 3, and 5 min after incubation with AuMu@pH3 (B) and AuMu@pH6 (C). D Cell viability of human foreskin fibroblasts (HFF) cells was measured through a fluorescein diacetate (FDA) metabolism assay after incubation with AuMu and irradiation for 3 min in order to simulate the treatment damage to the healthy skin surrounding tissue
