Nanomaterials in service of health: how copper iodide-based sensors help detect ammonia

Abstract

The presented research focuses on the development of nanostructured copper iodide (CuI) thin-film sensors for ammonia detection. The sensors show high sensitivity to low NH₃ concentrations (from 0.15 ppm) and excellent selectivity, even in humid conditions. Their flexibility and durability make them suitable for both environmental monitoring and non-invasive medical diagnostics.
