New Insights on the Size-Dependent Inhibition of Enzymes by Gold Nanoparticles

Abstract: Particle size might affect the inhibition behaviors of gold nanoparticles (AuNPs) on enzyme activity by influencing the density of binding sites (ρ), the association constant (K a), the steric hindrance of enzymes by AuNPs, the binding orientations of the enzyme on AuNPs, as well as the structural changes of enzymes. In previous studies, the effects of the above-mentioned factors, which could not be ignored in the applications of enzymatic electrochemistry, were often overshadowed by the effects of surface are… Show more

“…When Δ H and Δ S are less than zero, it indicates an exothermic process with a decrease in entropy. [ 90 ] This thermodynamically driven process suggests a favorable interaction between the NMNs and proteins. Conversely, when Δ H and Δ S are greater than zero, it signifies an endothermic process with an increase in entropy.…”
