Abstract
Retraction of ‘Novel 8,9-dihydroxy-7-methyl-12H-benzothiazolo[2,3-b]quinazolin-12-one multiwalled carbon nanotubes paste electrode for simultaneous determination of ascorbic acid, acetaminophen and tryptophan’ by Manzarbanou Asnaashariisfahani et al., Anal. Methods, 2012, 4, 3275–3282, https://doi.org/10.1039/C2AY25418B.
The Royal Society of Chemistry hereby wholly retracts this Analytical Methods article due to concerns with the reliability of the data.
The SEM image of CPE in Fig. 1A is the same as another SEM image published by the authors in another Analytical Methods paper.1 The authors have not been able to provide a satisfactory reason for how this occurred.
Given the significance of these concerns, the editor has lost confidence that the findings presented in this paper are reliable.
The authors were informed about the retraction of the article. Ali A. Ensafi, Hassan Karimi-maleh, Fatemeh Karimi and Mohammad A. Khalilzadeh have not agreed with the decision, the other authors have not responded.
