Description
Pan Wang and co-authors build a chip sensor that sniffs out traces of a veterinary antibiotic in minutes, in a 2023 paper. Enrofloxacin is used widely in farm animals, resists breakdown, and builds up as residue that threatens health and the environment. Their sensor pairs gold nanoparticles with aptamers, short DNA strands that grip the target drug.
Light bouncing off the particles shifts color as drug binds, a signal read on the chip. The device measured the drug from 0.01 to 100 nanograms per milliliter, and could sense as little as 0.001. Tests of interference, repeat use, and selectivity all passed. The authors pitch the chip as a cheap, steady field tool for residue checks in food and water.
