Description
José Carlos Santos-Ceballos and co-authors build a cheap ammonia sniffer that works at room temperature. Ammonia leaks threaten workers and the environment, and most sensors need heat to work well. Their device starts with laser-induced graphene, a porous carbon film burned into plastic by a laser, then coats it with the conducting polymer polyaniline.
Spectroscopy and microscopy confirmed the coating and structure of the composite. The authors say this pairing is used for gas sensing here for the first time. The result is a chemo-resistive sensor: its electrical resistance shifts as ammonia lands on it. They present the recipe as simple and low cost. It aims at flexible, wearable detectors that could ride on clothing or badges. Such sensors could watch the air continuously in farms, cold stores, and chemical plants.
