Fig. 4From: Design and site-directed compartmentalization of gold nanoclusters within the intrasubunit interfaces of ferritin nanocagea The fluorescence intensity of 3Cys-ΔC-templated Au NCs (black) and β-lactoglobulin-templated Au NCs (red) as a function of reacting time under basic conditions. b The two Au binding sites are located within four α-helix bundle of 3Cys-ΔC observed from side-view and top-view, respectively, and such a size-constrained microenvironment is necessary for preparation of Au NCsBack to article page
