Anthocyanins are natural colorants belonging to the flavonoid family. They widely distributed among flowers, fruits, and vegetables. Using automated oxygen radical absorbance capacity (ORAC) assay developed in our laboratory, we determined antioxidant of 14 anthocyanins including aglycons delphinidin, cyanindin, pelargonidin, malvidin, peonidin, their derivatives with different sugar linkages. Among these anthocyanins, kuromanin (cyanidin-3-glucoside) had highest ORAC activity, which was 3.5...
The most studied effect of surface-enhanced Raman scattering (SERS) hotspots is the enormous enhancement analytes therein. A less known effect, though, that formation may cause trapped to change molecular orientation, which in turn leads pronounced changes SERS fingerprints. Here, we demonstrate this by creating and characterizing colloidal solutions. Anisotropically functionalized Au nanorods were synthesized, whereby sides specifically encapsulated polystyrene-block-poly(acrylic acid),...
The core-shell nanoparticle structure, which consists of an inner layer "guest" encapsulated inside another a different material, is the simplest motif in two-component systems. In comparison to conventional single-component systems, complex systems pose both challenges and opportunities. this Account, we describe our recent progresses using for exploring new sophisticated nanostructures. Our discussion focused on mechanistic details, order facilitate rational design future studies. We...
We explored the use of PVP-Au NPs as nucleation seeds for zeolitic imidazolate framework-8 (ZIF-8) to selectively synthesize Au@ZIF-8 single- or multi-core-shell structures by epitaxial growth coalescence nuclei. Photocatalytic oxidation benzyl alcohol was studied based on LSPR-induced light absorption.
One-dimensional assembly of gold nanoparticles (see picture)is achieved by a sphere-to-cylinder transformation polymer shells. A large amount monomers remains after the assembly, which is characteristic chain-growth "polymerization". Single-line chains can be converted to double-line chains, thus substantiating unique role shell.
Human RNA-binding protein (HuR), a ubiquitously expressed member of the Hu family, plays an important role in mRNA degradation and has been implicated as key post-transcriptional regulator. HuR contains three RNA-recognition motif (RRM) domains. The two N-terminal tandem RRM domains can selectively bind AU-rich elements (AREs), while third domain (RRM3) contributes to interactions with poly-A tail target other ligands. Here, X-ray structure methylated (RRM1/2) their RNA-free form was solved...
Highly selective hydrogenation of molecules containing more than one reducible group is always challenging. Here we report an efficient strategy for rational preparation highly gold-based catalysts in the substituted nitroarenes by positioning gold nanoparticles on edge/corner sites anatase. Mechanistic studies reveal that catalyst with anatase could form unique adsorption and activation nitro groups, thus leading to high activity selectivity. This supported opens a new door design...
Forged signature threatens the authenticity of personal identity. Here, an effective SERS anti-counterfeiting system is designed for signatures. Mixed ligands improve complexity Raman spectra and expand coding capacity. Fourteen distinct combinations are created from mere five ligands, great expansion possible with modest ligand library. On other hand, (Au-aggregate)@Ag@PSPAA nanostructure significantly increases surface-enhanced scattering (SERS) intensity stability so that excellent...
