Abstract

An inexpensive, portable, hand held, point-af-care, non-invasive breath-analyzer for the detection of H. Pylori in adults and children by measuring ammonia in breath using a polyaniline-carbon nanotube sensor. In one embodiment, a detector utilizes a polyaniline (PANI) - carbon nanotube composite with an unlabeled urea as a substrate which detects the presence of ammonia in breath, and thereby detects the presence of H. Pylori.
