This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal).

This article has been retracted at the request of the Editor-in-Chief following concerns raised by a reader.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. 2E published in Biosensors and Bioelectronics Volume 73, 15 November 2015, Pages 234–244, https://doi.org/10.1016/j.bios.2015.06.005 as well as Fig. 3E from RSC Adv., 2014,4, 56690–56700, https://doi.org/10.1039/C4RA08875A.

This problem with the data 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.
