Description
Macroporous (glycidyl methacrylate) GMA-based composite was synthesized via suspension polymerization in the presence of 2 wt. % magnetic nanoparticles and functionalized with triethylenetetramine. Copper was immobilized on composite by contacting modified copolymer with 0.1 M solution of CuCl2, at pH 5, and 25 ̊C. The obtained composite was characterized by mercury porosimetry, Fourier transform infrared spectroscopy (FTIR) analysis and atomic force microscopy (AFM). GMA-based composites, due to their properties (size, porosity, etc.), and the presence of reactive epoxy group, have found a variety of applications as sorbents, enzyme supports, in biomedical applications, for metal and organic compounds sorption.1
The antimicrobial activity of the synthesized GMA/Cu copolymer against Staphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger as representatives for Gram-positive bacteria, Gram-negative bacteria, yeast and fungi were investigated in this study.2 The copolymer displayed good antimicrobial activity against all analyzed microbes, which makes it a material that can be potentially used for biomedical (antibacterial and antifungal) applications.
