Facile One-Step Synthesis of Nickel Sulphide Nanoparticles Decorated Poly (Acrylic Acid) Coated Multi-Walled Carbon Nanotube for Detection of Tenofovir in Human Urine
Tenofovir (TNF), a nucleotide analogue of adenosine 5′-monophosphate, is the first-line treatment for chronic HIV/hepatitis B coinfection. There is a need to explore highly sensitive, rapid, and cost-effective quality control techniques to detect the drug. Nickel sulphide @ poly(acrylic acid) coated multi-walled carbon nanotubes (NiS@PAA-MWCNT) composite was synthesized using the one-step solvothermal method. The composite was characterized by UV-vis spectroscopy, Fourier transforms infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and energy-dispersive X-ray spectroscopy. Morphological analysis showed polydispersed NiS on the surface of the poly(acrylic acid) coated multi-walled carbon nanotube (MWCNT). Tenofovir was electrochemically detected in human urine by differential pulse voltammetry (DPV) using the NiS@PAA-MWCNT modified glassy carbon electrode. The linear range was found to be from 20 to 80 µM with a limit of detection of 5.83 × 10−12 M and 5.12 × 10−12 M in phosphate buffer and human urine, respectively. The practical applicability of the modified electrode was evaluated in human urine and in the presence of different interfering agents. The electrode demonstrated good reproducibility, selectivity, and sensitivity. Thus, NiS@PAA-MWCNT nanocomposite can be used in electrochemical sensors for quality control purposes.
期刊介绍:
Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies.
Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
