Instability of Cationic Gold Nanoparticle Bioconjugates: The Role of Citrate Ions [J. Am. Chem. Soc. 2009, 131, 13320–13327]. Isaac Ojea-Jimenez and Victor Puntes* Page 13321. In the last paragraph of the Experimental Section, “Conjugation of Peptidic Biomolecules”, the decimal point was misplaced in the value given for the assumed surface area occupied by thiolated peptides. Our calculations assumed that each thiolated molecule occupies 21.4 Å2 of the AuNP surface, not 2.14 Å2. JA101213S 10.1021/ja101213s Published on Web 03/19/2010
