100% of bacteria bounce off surfaces coated with “flea-jumping protein” | It relies on the unique properties of resilin, a natural insect protein that enables fleas to jump hundreds of times their body length.
Researchers have developed a new method for preventing bacteria from adhering to surfaces, such as medical devices. It relies on the unique properties of resilin, a natural insect protein that enables fleas to jump hundreds of times their body length.
Led by researchers from RMIT University in Melbourne, Australia, a new study examining the applicability of a resilin-mimicking compound in healthcare found that it can be used to form an antibacterial coating that fully blocks bacteria from attaching to a surface. A coacervate is a soft, spherical, nano-sized droplet made from proteins (resilin in this case) that clump together in water, forming a separate phase (like tiny blobs), which coats surfaces and influences how cells or bacteria interact with them. “These early results are very promising as a new way to help improve infection control in hospitals and other medical settings, but now more testing is needed to see how these coatings work against a wider range of harmful bacteria,” said study author Professor Naba Dutta, from RMIT’s School of Engineering.
