Description
Mervin Chun-Yi Ang and co-authors present a study dated 2026 on a glowing sensor for a gut health marker. Gut bacteria turn the amino acid tryptophan from food into a compound called IPA. Levels of this compound may signal gut inflammation, but measuring it now needs costly lab machines.
Their sensor pairs a carbon nanotube with a charged polymer coating. The compound binds at the polymer, and the binding dims two kinds of glow: a visible one from the polymer and a near-infrared one from the tube. The infrared channel shines through tissue, while the visible one suits cheap screening at the point of care. Set in a soft gel, the sensor could one day track gut markers inside the body.
