Reusable Nanomaterial Rapidly Sterilizes Contaminated Milk and Water

Researchers have created a novel composite nanomaterial (MCOF@Au@PEI NPs) that effectively eliminates pathogenic bacteria in contaminated milk and water. This magnetic, gold-containing material integrates bacterial capture, photothermal sterilization, and magnetic separation, offering a sustainable alternative to traditional methods. Its reusability and efficiency could significantly improve food safety and access to clean water globally.
