Correction for ‘Folic acid-functionalized up-conversion nanoparticles: toxicity studies in vivo and in vitro and targeted imaging applications’ by Lining Sun et al., Nanoscale, 2014, 6, 8878–8883.


The original version of this article and the ESI unfortunately contained errors in Fig. 6 and Fig. S3. The corrected Fig. 6 is given below. The ESI which now includes the corrected Fig. S3 was republished on 1st September 2017. We confirm that these changes do not affect the scientific conclusions of the manuscript.

Fig. 6 Confocal luminescence images of [FR(+)] HeLa cells (a–d) and [FR(−)] MCF-7 cells (e–h) stained with UCNC-Er-FA nanocomposites (300 μg mL−1) for 1 h at 37 °C. For the competition experiments, [FR(+)] HeLa cells were first incubated with excess free FA and then UCNC-Er-FA nanocomposites under the same conditions (i–l). Fluorescent images were collected at the green (520–560 nm) channels and red (630–670 nm) channels.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
