A first adrenalone electrochemical sensor using a gold-nanoparticle/poly(pyrrole) composite-modified graphite electrode

Abstract

In this study, a pencil graphite electrode (PGE) modified with a composite of polypyrrole and Au nanoparticles (Au-NPs/PP/PGE) was developed and evaluated as a novel electrochemical sensor for the determination of adrenalone for the first time.

“…Gold nanoparticles (AuNPs) is one of the most attractive metal nanoparticles (NPs) due to their unique physical and chemical properties, good biocompatibility, high dispersibility, high stability, and low toxicity [1] , [2] , [3] . They have been used as the biomedicine (anti-cancer drug or drug carrier, cancer detection), biosensors, catalyst, and antimicrobial agents [1] , [2] , [3] .…”

They have been used as the biomedicine (anti-cancer drug or drug carrier, cancer detection), biosensors, catalyst, and antimicrobial agents [1] , [2] , [3] . Different physical and chemical approaches have been used to synthesize metal NPs, however, these methods are either not cost-effective, or need toxic chemical reducing agents which are harmful to environment.…”

“…Besides, PAni has special electronic properties, which can be reversibly controlled by the material's protonation/deprotonation processes (5). In addition, PAni has great potential for highend applications, such as electrodes (18,28,38,(75)(76)(77)(78)(79)(80)(81)(82)(83), batteries (15,(84)(85)(86)(87)(88)(89)(90)(91)(92)(93), microelectronics (94)(95)(96)(97)(98)(99)(100)(101)(102), electrochromic materials used in displays (103)(104)(105)(106)(107)(108)(109)(110), sensors (22,(111)(112)(113)(114)(115)(116)(117)(118), and electromagnetic shielding (119)(12...…”
