Abstract

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy). This article has been retracted at the request of the senior authors of the article; Jean-Luc Putaux and Bruno Jean. There are serious concerns about the reliability of the data presented in this article, which critically affects the main conclusions. Namely, TEM Figs. 3, 6 and 7 show signs of manipulation, such as the presence of repeated fragments and the use of the clone stamp tool applied with some image editing software. The first author of the paper, Fangbo Lin, was contacted regarding this matter but did not respond. The two above mentioned authors apologize for any inconvenience to readers.

Keywords: Cellulose nanocrystals; Gold nanoparticles; Microfibrils; Reducing end labeling; Transmission electron microscopy.
