The authors regret that the versions of Fig. 2 and ​and44 displayed in the original article were incorrect. The loading dye in Fig. 2c should be the artificial marker for molecular weight analysis. The original Fig. 4 did not support the EGFR binding due to the cell endocytosis, and the result has been revised with an improved data set.

(b) The bright field, and PL picture at different channels. After merging the PL picture of Dapi and GFP channels, the successful staining of membrane and nucleus was observed. The quantum yield of GQDs is much lower than Dapi, and we have to tune the contrast/brightness to reach the same quality between Dapi and GQDs. The emission of Dapi also has some signal in GQDs channel, and we have re-draw the data to get rid of the Dapi signal.The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
