The present work discusses the ammonia (NH3) sensing behavior of etched-tapered single mode fiber (SMF) sensors coated with polyaniline (PANI)/graphite nanofiber (GNF) nanocomposite at room temperature. SMF was etched with hydrofluoric acid and subsequently tapered in a glass processing workstation....
