Lysozyme-AuNPs Interactions: Determination of Binding Free Energy.
Gomes A, Carnerero JM, Jimenez-Ruiz A, Grueso E, Giráldez-Pérez RM, Prado-Gotor R. Gomes A, et al. Nanomaterials (Basel). 2021 Aug 22;11(8):2139. doi: 10.3390/nano11082139. Nanomaterials (Basel). 2021. PMID: 34443969 Free PMC article.
Lysozyme-AuNPs interactions induce aggregation of citrate-stabilized AuNPs at low concentrations by neutering the negative charges of citrate anions; from those aggregation data, the magnitude of the interactions has been measured by using Benesi-Hildebrand plots. However, …
