New Formaldehyde Sensor Detects Adulterated Fish

Recently, a breakthrough in the fight against food adulteration emerged as researchers at Guwahati University's Nanomaterials and Nanoelectronics Laboratory unveiled a cost-effective formaldehyde sensor.

  • This metal oxide-reduced graphene oxide (rGO) composite sensor exhibits non-invasive capabilities, effectively detecting formalin adulteration in fish at room temperature.

Key Points

  • Innovative Sensor Technology: The sensor, constructed from metal oxide nanoparticles and rGO composite, introduces a low-cost solution for detecting formaldehyde in fishes without invasive procedures.
  • Formaldehyde in Food: Formaldehyde, a colourless and pungent gas, is employed as a preservative in certain foods, particularly fish in developing nations. However, its use is illegal in many countries due ....
