Figure 2From: Investigation of antimicrobial activity of photothermal therapeutic gold/copper sulfide core/shell nanoparticles to bacterial spores and cellsThe percentages of surviving B. anthracis spores upon pre-treatment with Au/CuS NPs at 0.83 μM and 4.15 μM and treatment durations varying from 1 h to 24 h. Initial spore concentration: 105 spores/mL in DI water.Back to article page
