• •A new electrocatalytic sterilization method uses copper oxide nanowires to create alkaline microenvironments that kill bacteria.
• •The method is efficient, environmentally friendly, and operates at low voltage.
• •It avoids harmful by-products and high energy consumption associated with conventional methods.
• •The method effectively eliminates bacteria such as E. coli within minutes.

Researchers have developed a novel electrocatalytic sterilization method using copper oxide nanowires to generate highly alkaline microenvironments. This approach efficiently kills bacteria, like E. coli, by disrupting their cellular processes. Unlike conventional methods, it avoids harmful by-products and operates at low voltage, making it more sustainable. The new technique, developed by a team at Qingdao University, offers a promising starting point for developing safe and effective sterilization strategies.
