title: RETRACTED: A fluorescent molecularly-imprinted polymer gate with temperature and pH as inputs for detection of alpha-fetoprotein.
abstract: This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).
  This article has been retracted at the request of the Editor following concerns raised by a reader.
  The article reuses an electron micrograph from a previous publication while claiming that these are different particles.
  Fig. 1C/D were reused from Fig. 2B published in Biosensors and Bioelectronics, Volume 73, 15 November 2015, Pages 234–244, https://doi.org/10.1016/j.bios.2015.06.005.
  This problem with the data presented casts 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.
