"Fluorescent Nanotubes: Customized Biosensors for Bacteria and Virus Detection"

Researchers have developed modular optical sensors using fluorescent carbon nanotubes and DNA anchors to detect viruses and bacteria. The nanotubes are customized with DNA structures that create defects in their crystal structure, altering their fluorescence. By attaching detection units to the DNA anchors, the sensors can identify specific viral or bacterial proteins. The sensors demonstrated high selectivity and stability, making them suitable for diagnostic applications in complex environments.
