A team of Georgia Tech University scientists have designed a steel-and copper-based material that doesn’t need to be treated with detergents or antibiotics to remain bacteria-free. This unique property is the product of its surface geometry, which is etched with nanoscopic needles so small and sharp that they pierce bacteria’s cell wall, effectively killing it without the need for sterilization. This is a potentially revolutionary invention, as bacterial infections have become a major...
