“Versatile Dendrimer-Encapsulated Nanoparticles for Analytical Applications”


There are two main topics presented here. The first topic is the synthesis of dendrimer-encapsulated nanoparticles (DENs) and their useful properties for analytical applications. Specifically, we synthesized Pt DENs containing an average of 55 Pt atoms using amine-terminated 4th-generation polyamidoamine (PAMAM) dendrimers, which we denote as G4-NH2(Pt55). The synthesized G4-NH2(Pt55) exhibited peroxidase-mimetic activity, superior or at least comparable to that of natural peroxidase enzymes such as horse radish peroxidase (HRP), and thus could be utilized as peroxidase-mimetic labels for sensitive colorimetric assays. In addition, we synthesized Pt DENs using amine-terminated nth generation PAMAM (Gn-NH2, n = 6 and 4) dendrimers. The synthesized Pt DENs showed different sizes over the range of 1-3 nm, but were fairly uniform and monodispersed in size with subnanometer accuracy. Interestingly, we found the size-dependent catalytic activity of the Pt DENs having well-defined sizes with subnanometer accuracy for the enhanced chemiluminescence of the luminol/H2O2 system. We demonstrated the analytical versatility of the Pt DEN-catalyzed generation of chemiluminescence in oxidase-based analyses toward various oxidase substrates including choline, glucose, and cholesterol. The second topic is the functionalization of chip surfaces with DENs for fabrication of versatile chip-based analytical platforms. Two types of surface decoration methods will be mainly discussed: electrochemical decoration of glassy carbon and indium tin oxide surfaces, and covalent decoration of chemically converted graphene (CCG) surfaces. A brief description will be also presented how the chip-based analytical platforms can be applied as electrochemical, optical, and electrochemiluminescence (ECL) sensor chips based on the various transduction techniques.
