Source<\/strong>– This post is based on the article “New non-invasive formaldehyde sensor can detect adulterated fish at room temperature<\/strong>” published in “PIB<\/strong>” on 27th December 2023.<\/p>\n

Why in the News?<\/h2>\n

Researchers have developed a new cost-effective formalin sensor that can effectively detect the presence of formalin (solution of formaldehyde in water) in adulterated fishes.<\/p>\n

What is Formaldehyde?<\/h2>\n

1) Formaldehyde is a colourless, pungent gas that is used in a variety of industrial processes, including as a preservative in some foods, commonly in fish in developing countries.<\/p>\n

2) However its use in food is banned in many countries due to its carcinogenic nature.<\/p>\n

What are the Present Techniques for Detecting Formalin Adulteration in Fish?<\/h2>\n

1) Commercial formalin sensors for fish mainly rely on either electrochemical or colorimetric principles.<\/strong><\/p>\n

2) Electrochemical sensors, while widely employed, tend to be costly. Conversely, colorimetric sensors are more budget-friendly.<\/p>\n

3) However, both approaches are invasive, and they face challenges in achieving precise and selective detection, particularly at low levels<\/strong>.<\/p>\n

What is this New Non-Invasive Formaldehyde Sensor?<\/h2>\n

1)\u00a0The formalin sensor has been developed using tin oxide-reduced graphene oxide composite (rGO-SnO2) that can effectively detect the presence of formalin in adulterated fishes<\/p>\n

2) Reduced graphene oxide (rGO) is employed for detecting toxic gases, while tin oxide (SnO2) is extensively studied for its ability to detect formaldehyde.<\/p>\n

3) Advantages-
\na. The technique involves non invasive detection<\/strong> of formalin.
\nb. The sensor exhibits prolonged stability and a low level detection limit<\/strong>.
\nc. Its relatively cost effective<\/strong>.
\nd. Regarded as a breakthrough in the field of food adulteration.<\/p>\n
