Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Hydrogen tetrachloroaurate(III) trihydrate, is researched, Molecular AuCl4H7O3, CAS is 16961-25-4, about Anisotropic Bimetallic Core-Satellite-Poly(aniline) Nanohybrids for Detection of Autoantibodies.Name: Hydrogen tetrachloroaurate(III) trihydrate.
Bimetallic core-satellite nanoparticles are widely exploited in surface-enhanced Raman scattering (SERS)-based applications due to their enhanced optical properties compared to single-component metallic nanoparticles (MNPs). In addition, anisotropic hybrid nanostructures containing both MNPs and polymeric compartments constitute a new class of functional nanomaterials for photonic applications because they show different functionalities and physicochem. characteristics at two distinct compartments. Herein, synthesis of two kinds of anisotropic bimetallic core-satellite-poly(aniline) nanohybrids (ABCPNs) using small or polymeric ligand-coated gold nanospheres or gold nanorods as seeds is reported. The ABCPNs exhibit enhanced optical properties due to a local electromagnetic field generated in the narrow interparticle gap between core and satellite nanoparticles. Furthermore, a SERS-based quant. anal. of autoantibodies against cyclic citrullinated peptide using the ABCPNs as SERS nanoprobes for a diagnosis of early rheumatoid arthritis is demonstrated, suggesting that these multi-functional nanostructures will be potential for advanced SERS-based biosensors.
