The effects of Au/CuS NPs’ pre-treatment and continuous presence in medium on the growth of B. anthracis spores. (A) The representative growth curves of B. anthracis spores after being pre-treated with 0.0083 μM, 0.083 μM and 0.83 μM Au/CuS for 30 min and subsequent growth in nutrient broth without removing the NPs. (B) The comparison of the growth curves of B. anthracis spores pre-treated with 0.083 μM, 0.83 μM AuCuS NPs, when the NPs were removed before growth and when the NPs were in the presence in the growth medium. Initial spore concentration: ~107 spores/mL, pre-treated with NPs in DI water for 30 min.
