Highly efficient and reusable dendritic Fe3O4 magnetic nanoadsorbent for inhibition of bacterial growth
Source abstract
Abstract
Abstract We have demonstrated antibacterial activity of dendritic Fe3O4 magnetic nanoadsorbents (DMNA) against Gram positive (S. aureus, B. subtilis) and Gram negative (E. coli, P. aeruginosa) bacteria. These nanoadsorbents were nearly spherical with an average diameter 10 nm showed superparamagnetic behavior at room temperature with strong field dependent magnetic responsivity. The magnetic nanoadsorbents having terminal amino acids on the shell create exteriors functionalities with high densities of organic moieties (both amine and carboxyl) for capturing of various microorganisms. Depending upon the surface functionality, DMNA has strong antibacterial activity (∼97% killing efficiency) towards S. aureus even at very low concentration. In addition, these nanoadsorbents can be used as most efficient, separable and reusable materials for killing bacterial pathogens.
