Design of an Injectable β-Hairpin Peptide Hydrogel That Kills Methicillin-Resistant Staphylococcus aureus

A peptide-based, injectable hydrogel is designed that is inherently antibacterial and can kill methicillin-resistant Staphylococcus aureus (MRSA) on contact. Peptide gels can be used as coatings to inhibit MRSA infection or syringe-delivered to a contaminated surface where the gel kills MRSA on contact.
