Rapid and effective detection of pathogenic bacteria responsible for pandemics or epidemics is crucial for global health surveillance. We introduce an innovative method combining hierarchical nanostructures and a nuclease-responsive DNA probe to capture and detect harmful bacteria on-site. The 3D bacterial capturing nanotopographical trap (b-CNT) uses advanced nanocilia and network structures for quick (<30 seconds) and irreversible bacterial capture. The DNA probe allows highly sensitive and rapid (<1 minute) detection. The b-CNT is proven effective for detecting dangerous pathogens like Escherichia coli O157, Salmonella enteritidis, Staphylococcus aureus, and Bacillus cereus on kitchen tools and food samples. This system is a simple, fast, and portable solution for point-of-care testing.-Scientific Journal cover artdesign by scapiens
