摘要
This article has been retracted:please see Elsevier Policy on Article Withdrawal(https://www.elsevier.com/about/our-business/policies/article-withdrawal).This article has been retracted at the request of all the Authors,the Editor-in-Chief and the owner of the journal.The article has been retracted because of the authors recently re-conducted partly the experiments and found that the anti-bacteria behavior of Rb+was not reproducible.As shown in Fig.1(see enclosed file),at a centration as high as 200 mM,the addition of single Rb+does not show anti-bacteria effect.In Fig.2(see enclosed file),the authors prepared a mixed solution containing Rb+,Mg2+and Zn2+with concentrations close to those(12 h)in the article,and found that the mixed solution does not show anti-bacterial effect either.The two figures indicate that the anti-bacteria effect of Rb+is not conclusive,which seriously impairs the rigidity of the paper.Considering complex factors influencing the experiments with hydrogels,there might be other effects on the anti-bacteria behavior.However,since the anti-bacteria effect of Rb+is incorrect,the authors would like to retract the published article.
