Retraction: Synthesis of non-toxic, biocompatible, and colloidal stable silver nanoparticle using egg-white protein as capping and reducing agents for sustainable antibacterial application

Abstract

Retraction of ‘Synthesis of non-toxic, biocompatible, and colloidal stable silver nanoparticle using egg-white protein as capping and reducing agents for sustainable antibacterial application’ by Kalaiyarasan Thiyagarajan et al., RSC Adv., 2018, 8, 23213–23229, https://doi.org/10.1039/C8RA03649G.

I, the undersigned author, hereby wholly retract this RSC Advances article due to the following instances of matched/similar images that have been identified that weaken this article, which occurred due to honest human errors.

Following the previous publication of a correction to replace Fig. 3D, instances of duplicating images have been identified that undermine this article.

In Fig. 5, the panels E. coli MTCC No 62 6 μg ml⁻¹ and E. coli MTCC No 62 8 μg ml⁻¹ are identical. Furthermore, they are identical to panels in another article published by the authors in RSC Advances,¹ namely the panel for freshly prepared S. enterica MTCC-3219 2 μg ml⁻¹ 10⁻¹⁰ and the panel for S. typhirmurium MTCC-3224 4 μg ml⁻¹ 10⁻⁵ after one year of storage in Fig. 3 of ref. 1 and the panel 1 h treated with SBT@AgNPs in Fig. 7 of ref. 1.

Thiyagarajan Kalaiyarasan and Vijay K. Bharti responded to all enquiries and submitted data related to the above concern. However, to avoid any future ambiguity to the readers, the article is retracted.

Krishna Kumar and Vijay K. Bharti do not agree to the retraction. The other authors have been informed but have not responded to any correspondence regarding the retraction.
