Description
Kittidhaj Dhanasiwawong and co-authors present in 2026 a gold coated surface of tiny plastic spheres that makes Raman sensing more even and reliable. Such sensing boosts weak light signals from molecules, but poor wetting on old surfaces left uneven deposits and shaky readings. Their surface spreads water very well and can be tuned for stronger signals.
Tests with a dye probe showed a boost of about a hundred thousand fold and detection down to very low amounts. The team also detected trace levels of a toxic herbicide. Because the surface is made by a simple coating method, the authors present it as cheap and scalable for real sensing work.
