Formation Mechanism for Stable Hybrid Clusters of Proteins and Nanoparticles

Formation Mechanism for Stable Hybrid Clusters of Proteins and Nanoparticles - Citrate-stabilized gold nanoparticles (AuNP) agglomerate in the presence of hemoglobin (Hb) at acidic pH. The extent of agglomeration strongly depends on the concentration ratio [Hb]/[AuNP]. Negligible agglomeration occurs at very low and very high [Hb]/[AuNP].
