Retraction: Polymer nanodots of graphitic carbon nitride as effective fluorescent probes for the detection of Fe3+and Cu2+ions (Nanoscale (2014) 6 (4157–4162) DOI: 10.1039/C3NR06744K)

Abstract

The Royal Society of Chemistry, with the agreement of the authors, hereby wholly retract this Nanoscale article due to concerns with the reliability of the data in the published article. Repeating fragments can be observed in the TEM images in Fig. 1B and C, indicating that these images have been manipulated. The first author initially requested to retract this article because he admitted that Photoshop technology was used in the preparation of Fig. 1. The authors subsequently requested to correct the article based on updated experimental data. The authors apologize for any inconvenience to readers.
