Sterilization in waters is a worldwide issue. Herein, we successfully fabricate a new composite biomaterial (denoted shell-Ag) by embedding Ag-0 nanoparticles onto the hierarchical porous structure of Artemia shell using the in-situ deposition method. The resultant shell-Ag exhibits effectively antibacterial activity for both gram-negative bacterium Escherichia coli and the gram-positive bacterium Staphylococcus aureus and the complete sterilization process can be well achieved within 240 min and 360 min, respectively. The bactericidal tests on E. coli and S. aureus show that the MIC (Minimum Inhibitory Concentration) value for both bacteria ranged from 0.32 to 0.62 g/L, and the MBC values (Minimum Bactericidal Concentration) is approximately between 2.5 and 5 g/L. Four cycles tests demonstrate that the shell-Ag also presents the satisfactory Ag slow-release capacity and lasting duration. All the results suggest that the composited shell-Ag is a promising candidate as antibacterial materials. (C) 2016 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V.
