RETRACTED: Spectroscopic investigation of collagen scaffolds impregnated with AgNPs coated by PEG/TX-100 mixed systems

The article was a duplication of a paper that had already appeared in “Synthesis, characterization and comparison of antimicrobial activity of PEG/TritonX-100 capped silver nanoparticles on collagen scaffold”, Colloids Surf. B Biointerfaces, 90 (2012) 191-196, http://dx.doi.org/10.1016/j.colsurfb.2011.10.021. The authors would like to apologize for this administrative error on their part.
