Sensitive and selective electrochemical detection of acetaminophen based on GO-MnO2-modified electrode
This article describes an efficient electrochemical sensor based on a graphene oxide- manganese dioxide (GO-MnO2) nanocomposite for detecting acetaminophen (AAP) in human fluids. The MnO2-wrapped GO sensing element was prepared by a simple and environmentally friendly co-precipitation method. The prepared GO-MnO2 nanostructure was characterized for its structural, morphological, and functional properties and tested for AAP detection. At a pH of 3, the electrochemical results revealed a high redox process toward AAP due to the transfer of two electrons and protons between the GO-MnO2/glassy carbon electrode (GO-MnO2/GCE) and AAP. The differential pulse voltammetry (DPV) analytical results showed the precise sensing ability of AAP in a wide linear range [0.125–2000 µM] with superior anti-interference ability. The calculated sensitivity of the GO-MnO2/GCE was 17.04 µAµM−1 cm−2, and the detection limit (LOD) was 7.042 nM. The sensor exhibited high reliability, good reproducibility, and a good recovery range of 98.47–99.22% in human urine sample analysis.
期刊介绍：
Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
