title: RETRACTED: Graphene quantum dots decorated CdS doped graphene oxide sheets in dual action mode: As initiator and platform for designing of nimesulide imprinted polymer.
abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).
  This article has been retracted at the request of Editor following concerns raised by a reader.
  The article uses several electron micrographs which have been used in other publications as well denoting different samples.
  Fig. 2A was reused from Fig. 3A, Chemical Engineering Journal, Volume 299, 1 September 2016, Pages 244-254, 10.1016/j.cej.2016.04.051. According to the authors this was due to a mistake at the compilation of the manuscript (mixing images from the GO and Cds:GO samples).
  Fig. 2C was reused (a lower zoom level) from Fig. 1F, Biosensors and Bioelectronics, Volume 89, Part 1, 15 March 2017, Pages 620-626, 10.1016/j.bios.2015.12.085.
  The inset in Fig. 1F was reused from Fig. 2D, Environ. Sci. Technol., 2015, 49 (10), pp 6117–6126, 10.1021/acs.est.5b00182.
  These problems with the data presented cast doubt on all the data, and accordingly also the conclusions based on that data, in this publication.
  As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
