A new report in the Feb. 12 edition of ACS' Biomacromolecules describes a new method of producing a polymer which can be used in medical implants, wherein penicillin adheres to its surface and remains highly effective. In laboratory experiments, it has been demonstrated that the penicillin-coated surfaces showed highly effective antibacterial activity against Staphylococcus aureus, which causes many serious antibiotic-resistant human infections.

Such a polymer that supports antibacterial coatings may be useful in manufacturing medical implants, including contact lenses, vascular grafts and other reconstructive surgery procedures.
