Correction: Atom-precise fluorescent copper cluster for tumor microenvironment targeting and transient chemodynamic cancer therapy

Abstract

Figures

In vivo cancer chemotherapy results of Cu_6_NC. All mice were randomly divided into 3 groups: normal control group (Control), Cu_6_NC group (10 mg/kg), and Cu_6_NC (20 mg/kg), at the same time, were treated by intraperitoneal injection of the corresponding dose of Cu_6_NC. a Photographs of mice after 16 days of different formulations. b Tumor growth curves of mice in different treatment groups. c Ki67 staining and TUNEL staining of tumor sections from different treatment groups. Scale bar: 100 μm. d Comparison of tumor weight in mice after therapy. The quantitative analysis of Ki67 e and TUNEL

In this article the wrong figure appeared as Fig. 4. The kidney data was inadvertently duplicated from liver by mistake, and the data for 20 mg/kg group of heart was inadvertently duplicated from 10 mg/kg group in Fig. 4g. The correction of this information does not affect the results and conclusions of this paper. The corrected image of Fig. 4 is provided below.
