Multi walled carbon nanotubes supported CuO-Au hybrid nanocomposite for the effective application towards the electrochemical determination of Acetaminophen and 4-Aminophenol

Development of an Efficient Voltammetric Sensor for the Monitoring of 4-Aminophenol Based on Flexible Laser Induced Graphene Electrodes Modified with MWCNT-PANI

“…Therefore, pH 6.5 was selected as a supporting electrolyte in all the experiments for the determination of 4-AP. On increasing the pH of PBS solution, the oxidation peak potentials of 4-AP shifted towards the negative potential, which indicates the involvement of the protons in the electrochemical oxidation of 4-AP at LIC/MWCNT-PANI electrode [ 32 ]. The possible redox reaction mechanism is presented in inset Figure 7 d.…”

“…The fabricated sensor shows a detection limit of 2 nM in the linear range from 2 to 8 nM [31]. P. Shaikshavali et al [32] succeeded in elaborating a hybrid nanocomposite based on CuO-Au decorated multiwalled carbon nanotubes (MWCNTs) and employed as sensitive material for the detection of 4-AP after its dispersion on the surface of glassy carbon electrode (GCE). The developed sensor showed a good linear response for 4-AP at the range of concentration from 0.5 µM to 1.6 µM with a detection limit of 0.105 µM.…”

Non-enzymatic electrochemical determination of salivary cortisol using ZnO-graphene nanocomposites

“…30 In another study, Shaikshavali and co-workers reported the fabrication of MWCNTs supported CuO-Au hybrid nanocomposite for the effective application towards the electrochemical determination of acetaminophen and 4-aminophenol with detection limits of 0.016 mM and 0.105 mM respectively. 31 Palanisamy et al reported a novel reduced graphene oxide/ZnO composite modied electrode for nonenzymatic H 2 O 2 sensing. 32 In this present investigation, the authors have reported a facile, economic, and highly efficient electrochemical sensor for quantitative analysis of cortisol in human saliva.…”

The fabrication of a novel polyacrylonitrile/reduced graphene oxide-amino-halloysite/bimetallic metal–organic framework electrospun nanofiber adsorbent for the ultrasonic-assisted thin-film microextraction of fatty acid methyl esters in dairy products with gas chromatography-flame ionization detection

“…24 Recently, a considerable body of research has suggested that combining MOFs with different functional materials, such as carbon nanotubes (CNTs), graphene oxide, graphite oxide, and carbon nanobers to prepare different composites, can signicantly enhance their performance. [25][26][27] GO is composed of distorted graphene layers, carbonyl, hydroxyl, and epoxy groups on the basal planes and carboxylic functionality on the edges of the carbon sheets. 28 All of these mentioned factors acidify the material and make it highly hydrophilic, which explains its easy delamination in alkaline or alcohol solutions.…”
