Description
Natália Caldas and eleven co-authors print a sensor electrode from a custom plastic filament in a 2026 paper. Cheap printed sensors could test drugs, patients, and river water on the spot, but plain printed carbon is a sluggish sensing surface.
Their filament blends graphite and plastic with bismuth oxide nanoparticles, printed into electrodes that need no extra activation step. Electrical tests showed charge crossing the surface far more easily after the addition. The sensor's response to paracetamol, a common painkiller, grew stronger and came at lower voltage. It read the drug across a wide range with a low detection floor. The same platform targets lead, aiming at one device for pharmacy, clinic, and field checks.
