title: RETRACTED: Designing of carbon based fluorescent nanosea-urchin via green-synthesis approach for live cell detection of zinc oxide nanoparticle.
abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).
  This article has been retracted at the request of Editor following concerns raised by a reader.
  There are significant concerns regarding the originality of the electron micrographs displayed in Fig. 1 (panels B-G, especially C). The concern is that these multi-particle images are comprised of copies of the same particles.
  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
