Scientists in Australia have developed a smart, bacteria-repelling coating based on resilin the ultra-elastic protein that gives fleas their legendary jumping power. When applied to surfaces like medical implants or surgical tools, the engineered resilin forms nano-droplets that physically disrupt bacterial cells, including antibiotic-resistant strains like MRSA, without harming human tissue. In lab tests, the coating was 100% effective at keeping bacteria from sticking and forming biofilms, a key cause of infection after surgery.
