Description
Sithara Soman and Kala build a glowing polymer that sniffs out an explosive acid. Their 2025 paper makes a silane polymer hung with naphthalimide pendants, then swaps one ring spot to brighten its glow. The tuned polymer dissolves better and shines with about twenty-three percent quantum yield. Its light shifts with the solvent around it.
Picric acid, a nitro explosive, dims the glow in a dose-wise way at tiny levels in water. The sensor caught amounts down to a few tens of nanomoles per liter. Timing tests showed a mixed dimming path. A thin film version worked too, thanks to the silane grip. The authors pitch it for field checks of nitroaromatic hazards.
