New microchip captures exosomes, enabling faster and more sensitive lung cancer detection from blood collection

The twisted disc shape of gold nanoparticles creates chirality, or asymmetry, and ensures strong interaction with light. A cavity in the center, less than 100 nanometers wide, helps the nanoparticles trap exosomes.
