Abstract
Pathogenic bacteria which cause infections and food poisoning are a major public health problem. Methods for the rapid detection and their identifications are required to prevent and diagnose these diseases. The high signal enhancement capability of biological sensors has spurred considerable efforts in developing antenna systems based on metal nanoparticles. Gold nanoparticles (Au NPs), which exhibit excellent elastic light-scattering properties, are expected to be utilized as an optical nanoantenna for bacterial detection.
