Self-Healing Antibacterial Coating Could Revolutionize Device Protection

Researchers develop transparent self-healing coating with antibacterial properties using dynamic selenonium salts. The material repairs scratches under heat while preventing bacterial growth, maintaining clarity for device screens and marine sensors.

This development matters because it addresses multiple real-world problems simultaneously: scratched phone screens, bacterial contamination on public surfaces, and marine biofouling that costs industries billions annually. Traditional coatings either heal damage once or resist bacteria but rarely do both while maintaining transparency. This innovation could extend device lifespans, reduce maintenance costs for ships and medical equipment, and potentially lower infection risks on frequently touched surfaces. As consumers increasingly demand durable, sustainable products and industries face pressure to reduce chemical leaching and waste, this coating represents a significant step toward multifunctional materials that serve both practical and environmental needs.
