A simple and highly selective electrochemical method was developed for the single or simultaneous determination of dopamine (DA) epinephrine (EP) in human body fluids using a glassy carbon electrode modified with nickel oxide nanoparticles nanotubes within dihexadecylphosphate film square-wave voltammetry (SWV) differential-pulse (DPV). Using DPV proposed electrode, separation ca. 360 mV between peak reduction potentials DA EP present binary mixtures obtained. The analytical curves showed an...
Abstract In this work, a simple and highly selective voltammetric method was developed for the simultaneous determination of paracetamol (PCT) codeine (COD) in pharmaceuticals human body fluids employing glassy carbon electrode modified with black (CB) nickel oxide nanoparticles (NiONPs) within dihexadecylphosphate (DHP) film. Using square‐wave voltammetry (SWV), separation ca. 550 mV between oxidation peak potentials PCT COD obtained. The presented linear concentration range from 3.0 to...
Abstract Bisphenol A (BPA) is an environmental endocrine disrupting chemical, which can lead to various adverse health effects. Aiming develop effective tools for the detection of BPA, this work reports a low cost and stable film based on casein (CAS) Carbon Black (CB). The proposed material (CAS‐CB) showed structures CAS surrounded by CB agglomerates observed Scanning Electron Microscopy while Fourier Transform Infrared Spectroscopy analysis illustrated characteristic bands casein. Cyclic...
The modification of a glassy carbon electrode with multi-walled nanotubes and gold nanoparticles within poly(allylamine hydrochloride) film for the development biosensor is proposed. This approach provides an efficient method used to immobilize polyphenol oxidase (PPO) obtained from crude extract sweet potato (Ipomoea batatas (L.) Lam.). principle analytical based on inhibitory effect sulfite activity PPO, in reduction reaction o-quinone catechol and/or sulfite. Under optimum experimental...
