Abstract

After the emergence of multidrug-resistant strains, antibiotic resistance in bacteria has become an important problem. Thus, materials for combating multidrug-resistant bacteria are of vital importance. In this work, we developed an antibacterial material that can selectively capture and destruct bacteria on the basis of their physical characteristics. To achieve bacterial capture and deactivation with a single material, we used bacterial cells as templates to synthesize surface-imprinted polymer beads in bacteria-stabilized Pickering emulsions. Acrylate-functionalized polyethylenimine was used to coat the bacterial surface so that the coated bacteria can act as a particle stabilizer to establish an oil-in-water Pickering emulsion....

After the emergence of multidrug-resistant strains, antibiotic resistance in bacteria has become an important problem. Thus, materials for combating multidrug-resistant bacteria are of vital importance. In this work, we developed an antibacterial material that can selectively capture and destruct bacteria on the basis of their physical characteristics. To achieve bacterial capture and deactivation with a single material, we used bacterial cells as templates to synthesize surface-imprinted polymer beads in bacteria-stabilized Pickering emulsions. Acrylate-functionalized polyethylenimine was used to coat the bacterial surface so that the coated bacteria can act as a particle stabilizer to establish an oil-in-water Pickering emulsion. Hydrophobic Ag nanoparticles were introduced into the oil phase composed of cross-linking monomers. Bacteria-imprinted beads (BIB) were obtained after the oil phase was polymerized. Bacterial binding experiments confirmed the importance of the imprinted sites for specific recognition with the target bacteria. The Ag nanoparticles embedded inside the polymer beads enhanced bacterial inactivation and reduced the leakage of heavy metal in aquatic environment. The combination of bacteria-imprinting with delivery of general-purpose antibacterial reagents offers a useful approach toward selective capture and destruction of bacteria.
