Dragonfly wings are covered with tiny nanopillars that have been shown to physically rupture bacterial cell walls upon contact, providing a natural antibacterial surface without the use of chemicals. This unique property has inspired the design of synthetic surfaces that replicate the nanopatterns found on dragonfly wings to prevent bacterial colonization. These surfaces are used in medical devices, hospital equipment, public transportation, and other high-touch areas where maintaining hygiene is critical. The dragonfly-inspired technology provides a passive, long-lasting antibacterial solution that reduces the need for disinfectants and antibiotics, helping to combat the spread of infections, including antibiotic-resistant strains. By leveraging the natural defense mechanisms of dragonfly wings, these surfaces offer an innovative and sustainable approach to improving sanitation and public health in various settings.
