Correction to: Multilayered controlled drug release silk fibroin nanofilm by manipulating secondary structure (Biomacromolecules (2018) 19: 7 (3096-3103) DOI: 10.1021/acs.biomac.8b00687)

We found an error in the Table of Contents and graphical abstract image and in Figures 1a and 4a. Heparin has an incorrect chemical structure. We modified the chemical structure of heparin and have provided the corrected graphics below. Page 3098, fifth line, right column: We made a mistake about the amine group of silk fibroin at pH 3. Because there are no arginine and lysine in the amino acid sequence of silk fibroin, NH3 + should be replaced with NH2 + in the positively charged silk fibroin. In Figures 2 and 3, the legends of the horizontal axis should read "wavenumber". We regret these errors and apologize for any inconvenience caused. (Figure Presented).
