Abstract
Correction for ‘Biogenic synthesis of copper oxide nanoparticles: comprehensive in vitro profiling for cervical cancer treatment and antibacterial strategies’ by Gouranga Dutta et al., New J. Chem., 2024, 48, 10697–10716, https://doi.org/10.1039/D4NJ01194E.
The authors regret errors in Fig. 5 and in Fig. 7.
In Fig. 5 the incorrect images were used for 50 µg/mL 24-hour/PC and 50 µg/mL 48-hour/BF. The corrected figure is shown here.

| Fig. 5 Morphological changes of HeLa cells after treatment with the green-synthesized CuO NPs. Photographs were taken with an inverted microscope (10×) and bright-field microscope (10×) at distinct time points (24 and 48 h). The upper panel represents the phase-contrast images, and the lower panel represents the bright-field (BF) images. The cells were stained with giemsa to visualize them under a bright-field microscope. All the images were taken at 10× the microscope’s objective (scale bar: 100 µm). PC: phase-contrast and BF: bright-field. (A) Control, (B) 30 µg mL−1, (C) 50 µg mL−1, and (D) 200 µg mL−1. | ||
In Fig. 7(A) the incorrect image was used for the bottom panel for the control. The corrected figure is shown here.

Fig. 7 Colony formation assay or clonogenic assay. (A) Photographs of the colony formations of different groups (control, 30, 50, and 200 µg mL−1), above panel and below panel signify the microscopic images of the colonies formed at distinct groups. The images were taken at 10× objective of the microscope (scale bar: 100 µm), (B) and (C) quantitative analysis of the colony formation. (B) No of colonies calculated for different groups, (C) percentage of colony formation for different groups calculated from the OD values of the samples. Data are represented as the mean ± SD [*![[thin space (1/6-em)]](https://www.rsc.org/images/entities/char_2009.gif) represents p < 0.05, **represents p < 0.01, and ***represents p < 0.001]. | ||
