Lead detection goes natural with these wood chips. As a wood-based microfluidic chip, the new technology uses microwave and colorimetric spectroscopy to detect lead with high sensitivity. When water flows through the chip, lead ions from the water react with a chemical reagent in the microfluidic channel, causing a color change from yellow to pink that can be read by a camera or spectrometer. The new chip provides an environmentally-friendly alternative to monitoring lead while also demonstrating that renewable materials can be used for high-precision detection. #OPG_AO #environment #chips #renewable Read more in our Newsroom! #OPG_AO #environment #chips #renewable
