Abstract

Correction for ‘Bifunctional scaffolds for the photothermal therapy of breast tumor cells and adipose tissue regeneration’ by Guoping Chen et al., J. Mater. Chem. B, 2018, 6, 7728–7736.

The authors regret that six incorrect images were used in Fig. 4a, d, f and i and Fig. 6a and c of the original manuscript, and the labelling of samples S1 and S2 was missing in the original Fig. 6. The correct versions of Fig. 4 and 6 are shown below. The captions for these figures remain unchanged.

Fig. 1 Live/dead staining of breast tumor cells (MDA-MB231-Luc cells) cultured in the gelatin scaffold (a, d and g), 2.0 mM AuNRs–gelatin scaffold (b, e and h) and 4.0 mM AuNRs–gelatin scaffold (c, f and i) without (a–c) and with NIR laser irradiation (d–i) at a laser power intensity of 1.3 W cm−2 for 8 minutes (d–f) and a laser power intensity of 1.6 W cm−2 for 6 minutes (g–i). Green color indicates live cells stained by calcein-AM while red color indicates dead cells stained by PI. Viability of the MDA-MB231-Luc cells cultured in the gelatin scaffold and AuNRs–gelatin composite scaffolds after irradiation for different times with a laser power intensity of 1.3 W cm−2 (j) and 1.6 W cm−2 (k). S1, S2 and S3 indicate gelatin scaffold, 2.0 mM AuNRs–gelatin scaffold and 4.0 mM AuNRs–gelatin scaffold, respectively. The data are presented as mean ± standard deviation, n = 3. No significant difference: N.S.; significant difference: *[thin space (1/6-em)]p < 0.05; **[thin space (1/6-em)]p < 0.01; ***[thin space (1/6-em)]p < 0.001.

Fig. 2 Photographs of mice subcutaneously implanted with the MDA-MB231-Luc cells/gelatin scaffold and MDA-MB231-Luc cells/2.0 mM AuNRs–gelatin scaffold constructs before irradiation (a and c) and after NIR laser irradiation at a laser density of 1.6 W cm−2 for 8 minutes (b) and a laser density of 1.3 W cm−2 for 10 minutes (d).
