The numbers of colony forming units of C. neoformans (H99) were determined after treatment with different concentrations of Pd@Ag NSs alone or combined with drugs for various periods of time. A. The Pd@Ag NSs treated group. B. The group treated with Pd@Ag NSs in combination with amphotericin B (1 μg/mL). C. The group treated with Pd@Ag NSs in combination with fluconazole (8 μg/mL). Experiments were performed in triplicate, while no drug treatment was used on the control group. The numbers in the brackets denote concentrations (μg/mL).
