Rapid Colorimetric Sensor for Detection of Bacteria in Water

Primary Inventors: 

This technology provides nanoparticle-based colorimetric sensors in a test strip format for rapid detection of bacteria in water. In the presence of bacteria, the bacteria-nanoparticle interaction interferes with nanoparticle-dependent colorimetric reaction, leading to a visible output. Unlike other test strip products for bacterial detection, the test strips provided by this technology are very easy to use, have high shelf stability and detection sensitivity, and can be used for detection of a broad range of bacteria. In addition, these test strips can be produced using a high-throughput manufacturing process at minimal costs. 

  • Rapid detection of bacteria in recreational water
