resilin Protein Used to Fight Bacteria on Medical Implants
Updated June 3, 2025
Australian researchers have discovered that a protein responsible for the elasticity of fleas, known as resilin, can be used to create antibacterial coatings. These coatings show promise in preventing infections associated with medical implants, according to a new study.
The RMIT university-led study marks the first reported instance of using antibacterial coatings derived from resilin-mimetic proteins to completely prevent bacteria from adhering to surfaces.This innovative approach could substantially reduce the risk of post-surgical infections.
Professor Namita Roy Choudhury, the study’s lead author, emphasized that this discovery is a crucial step toward developing smart surfaces that can prevent the growth of hazardous bacteria, including antibiotic-resistant strains like MRSA, on medical implants. The antibacterial coatings can be adjusted to combat bacteria effectively over extended periods,she noted.
Post-surgical implant infections, frequently enough requiring antibiotic treatment, are a growing concern. With increasing antibiotic resistance,preventative measures are becoming increasingly vital. The resilin-based coating is designed to prevent initial bacterial attachment and biofilm formation, thus decreasing infection rates.
Potential applications for this technology include spray coatings for surgical tools, medical implants, catheters, and wound dressings.
Resilin’s exceptional elasticity, resilience, and biocompatibility make it ideal for applications requiring flexible and durable materials. Its non-toxic nature further enhances its suitability for medical applications.
The team created various coatings from altered forms of resilin and tested their interactions with E. coli bacteria and human skin cells under laboratory conditions. The study revealed that resilin coacervates were 100% effective in repelling bacteria while integrating well with healthy human cells, a critical factor for medical implant success.
Dr. Nisal Wanasingha, another lead author from RMIT, explained that the nano droplets’ high surface area allows them to effectively interact with and repel bacteria. The coating disrupts bacterial cell membranes through electrostatic forces, leading to cell death.
Wanasingha added that the resilin-based coatings offer advantages over traditional methods. Unlike antibiotics, which can lead to resistance, the mechanical disruption caused by resilin coatings may prevent bacteria from developing resistance mechanisms. Furthermore,resilin’s natural origin and biocompatibility reduce the risk of adverse reactions in human tissues and are more environmentally friendly than alternatives like silver nanoparticles.
“This work shows how these coatings can be adjusted to effectively fight bacteria — not just in the short term, but possibly over a long period,” Choudhury said.
Professor naba Dutta, a study co-author, noted that resilin-mimetic protein is highly responsive to environmental stimuli, making it potentially tunable for various functions. Further testing is needed to assess the coatings’ effectiveness against a broader range of harmful bacteria.
What’s next
Future research will focus on attaching antimicrobial peptide segments during recombinant synthesis of resilin-mimics and incorporating additional antimicrobial agents to broaden the spectrum of activity. Transitioning to clinical use will require ensuring formula stability and scalability, conducting safety and efficacy trials, and developing affordable production methods.
