Description
Huanhuan Yang and co-authors build a glowing sensor for a food toxin in a 2023 paper. Aflatoxin B1 is a poison made by molds that can contaminate food, and checking for it guards public health. Their sensor uses a short DNA strand that folds when it meets the toxin, plus a dye that glows when its molecules clump.
A carbon material in the mix normally dims the dye. When the toxin is present, the folded DNA sticks to the carbon and shields the dye, so the glow survives and its strength reveals how much toxin is there. The test runs in two hours, spots very low levels, ignores other mold toxins, and worked in soy sauce samples with accurate recovery.
