Aquatic chemical sensors have experienced rapid development in recent years largely due
to advances in the fields of nanotechnology. Accurate in situ monitoring of nutrients is …

Polyaniline is an organic semiconductor. It is prepared by the oxidative chemical or
electrochemical oxidations of aniline in acidic aqueous media. The course of the oxidation …

The present work reported the polyaniline (PANI) and multiwalled carbon nanotube
(MWCNT)-based nanocomposite as a sensing material for the determination of aqueous …

Molecular imprinting focuses on the fabrication of an artificial receptor with perfect molecular
recognition abilities. It has attracted a great deal of scientific attention because of the …

We demonstrate an ammonia sensor composed of a tapered multimode fiber coated with
polyaniline nanofibers that operates at room temperature (26° C). The optical properties of …

The polyaniline thin films were prepared by in situ chemical polymerization of aniline on
polyethylene terephthalate substrate in the aqueous solutions of citric acid with ammonium …

Fiber optic sensor technology has been under development for the past 40 years and has
resulted in the production of various devices, including fiber optic gyroscopes; sensors of …

Here, we provide the first experimental evidence of proton release from polyaniline (PANI)
films subjected to anodic potentials at environmental pHs. We conducted an extensive …

In this paper, we presented a novel, compact, conceptually simple, and fully functional low-
cost prototype of a pH sensor with a PANI thin film as a sensing layer. The PANI deposition …

We report a simple, in-expensive, portable, and ultrasensitive optical sensor for detection of
ammonia in parts per million levels using magnetic nanofluids. The sensor produces visually …
