“The authors regret that an error appeared in Section 4.2.1 of the above-mentioned article. The authors would like to apologize to the readers of the article for any inconvenience caused due to this error. The correction follows here: 4.2.1. Effect of pH In this section, the line “At low pH values, there exists a strong electronegative repulsion between the positively charged dye ions and the negatively charged biosorbent surface due to the protonation of the surface functional groups resulting in low dye removal efficiency” should be read as “At low pH values, there exists a strong

electrostatic repulsion selleck screening library between the positively charged dye ions and the positively charged biosorbent surface due to protonation of the surface functional groups resulting in low dye removal efficiency”. “

author would like to bring to your attention that there are a couple of places of incomplete or incorrect citing of sources of references in the paper, and these are listed below: Page 191 • “Collagen is widespread in nature and plays an important role in the formation of tissues and organs. The ease of preparation has made it the most widely used biomaterial [1]. The above should be written as “Collagen is widespread in nature and performs a vital role www.selleckchem.com/products/Docetaxel(Taxotere).html in the tissues and organ formation [1]. The ease of preparation has made it the most widely used biomaterial.” • “Scaffolds made of collagen are distinct from those of synthetic polymers

mainly in its mode of interaction in the body [4]. Collagen is a good surface-active agent and its ability to penetrate a lipid-free interface has been demonstrated [5]. Compared with other natural polymers such as, albumin and gelatin, collagen exhibits superior biodegradability, biocompatibility and weak antigenecity [1, 6, 7]. In addition to the above mentioned advantages, collagen is non-toxic and has a good safety profile as a scaffold in the biomedical BCKDHA application such as tissue regeneration. The above should be written as “Scaffolds made of collagen differ from that of synthetic polymers in the manner they interact within the host body [4]. Collagen (M.W. 50,000) behaves as surface-active agent and is permeable through interfaces devoid of lipids [5]. In comparison to some of the existing natural polymers namely albumin and gelatin, collagen shows better biodegradability, biocompatibility and also reduced antigenecity [1, 6, 7]. In addition to the above mentioned advantages, collagen is non-toxic and has safety profile suitable enough to be used as a scaffold in the biomedical application such as tissue regeneration [7].” • “In recent years, silver nanoparticles (AgNPs) have attracted much attention and have been widely used in biomedical research. Synthesis of AgNPs has been of considerable interest during the past few decades as they exhibit better antimicrobial activity compared to metallic silver.
