Copper nanoparticles that glow in the dark are being tweaked so they shine brighter and last longer inside tiny point‑of‑care test kits. Scientists are using two tricks: covering the particles with a protective polymer (polyacrylic acid) and letting them clump together when special metal ions are ad
A fresh idea tackles a growing need. As more places allow cannabis use, people want to know how much THC is in the air. This new tool can help by spotting tiny amounts of the active compound. The sensor works differently from older gadgets. It uses a special screen‑printed graphene electrode that h
