Journal of Nanotechnology has retracted the article titled “Green Synthesis of Silver Nanoparticles Using Polyalthia longifolia Leaf Extract along with D-Sorbitol: Study of Antibacterial Activity” [1]. As raised on PubPeer, the article was found to contain images with signs of duplication and manipulation in Figures 3 and 4. The background of Figure 3 shows repeating features. In Figure 4, (b) in the top row is identical to (a) in the bottom row. Additionally, (b) and (c) in the bottom row of Figure 4 are identical to (c) and (b) in Figure 7 in another article by the same group of authors [2].
