Antibacterial study of Mg(OH)2 nanoplatelets

Abstract It was reported previously that Mg(OH) 2 nanoplatelets are effective antibacterial agent [1] . This paper further studied the mechanism study of Mg(OH) 2 nanoplatelets against Escherichia coli . Both experimental results and SEM analysis indicated that the membrane of the bacterial cell was destroyed by the direct contact with the Mg(OH) 2 nanoplatelets, leading to the cell death. In addition, UV illumination could further improve the antibacterial efficiency of Mg(OH) 2 nanoplatelets. Compared with other nanoparticles, it was also found that Mg(OH) 2 nanoplatelets have higher antibacterial efficiency, implicating their great potential application in biological control.
