Nanoscale sensors have been emerging as a feature of recent nanotechnology applications for food safety and quality measurement. Scientists are using nanotechnology for a rapid detection of Salmonella in foods. Here are two recent scientific findings:
- Dutch Bionanotechnology Centre for Food and Health Innovations used nanoparticles to build devices that sense the DNA of microbes such as Salmonella or Listeria (CBC, March 2009). Read more…
- US Department of Agriculture’s Research Service (ARS) and University of Georgia developed a nanorod-based biosensor that enables rapid detection of the Salmonella pathogen with high sensitivity. The sensor include fluorescent organic dye particles attached to Salmonella antibodies; the antibodies latch onto Salmonella bacteria and the dye lights up like a beacon, making the bacteria easier to see. (Food Production Daily, January 2009). Read more…
