To achieve ultrasensitive detection of trace targets through solution-based surface-enhanced Raman spectroscopy (SERS), direct adsorption the target molecules on a SERS-active surface is vital. In this work, cetyltrimethylammonium bromide (CTAB)-capped gold nano-bipyramids (Au BPs) with different aspect ratios (ARs) are prepared and successfully modified by simple ligand exchange method. Cysteamine-capped (cyst-Au obtained means replacement CTAB cysteamine using Au-S covalent bonding applied...
Abstract Since its discovery in 1997, the single molecule surface‐enhanced Raman spectroscopy (SM‐SERS) has attracted wide interest owing to enormous potential many fields. However, commercialized applications of SM‐SERS are still limited by lack a clear understanding relevant mechanism famous experiments. In this study, salt‐gradient model is proposed deeply investigate physical nature and update insights into morphological, structural, component evolution processes Ag NPs from dispersed...
In 1997, the discovery of single molecule–surface enhanced Raman spectroscopy (SM-SERS) rekindled broad interests owing to its ultrahigh enhancement factor up 1014–1015 level. However, regretfully, advantage SM-SERS with an ultralow detection limit has not yet been fully utilized in commercialized applications. Here, we report a strategy, which name confined-enhanced spectroscopy, overall properties can be remarkably improved situ-formed active nanoshell on surface silver or gold...
Tumor exosomes, known as maternal cell messengers, play an important role in cancer occurrence, proliferation, metastasis, immune escape, drug resistance, and other processes are entry point for research. However, there is still a lack of efficient detection technology exosomes. In this study, the ultrahigh sensitivity SERS nanoprobe with three dimensional (3D) magnetic core/Au nanocolumn/Au nanoparticles shell strongly coupling multistage structure (Fe
Abstract The heterogeneity of extracellular vesicles (EVs) surface information represents different functions, which is neglected in previous studies. In this study, a label‐free SERS analysis approach demonstrated to study fundamental EV biological and physical by matching specific sizes nano‐enhanced particles. This strategy reveals informative, comprehensive, high‐quality spectra the overall exosome surface, effectively circumvents key loss caused spatial resistance NPs binding 293...
Active points of noble metal nanocatalysts possess high catalytic activity and selectivity, but the reagent molecules are hard to confine exactly at small active in practical reaction system. Here, we developed a nano-driven confined catalysis strategy applied it plasmon-enhanced with Au nano-bipyramids (NBPs) as catalyst. The theoretical calculation indicates that electric field lines converge just hot spots surface-charged NBPs. Accordingly, our strategy, reactant driven into sites by...
The ability to engineer the surface ligands or adsorbed molecules on colloid nanocrystals (NCs) is important for various applications, as physical and chemical properties are strongly affected by chemistry. Here, we develop a facile generalized ionic compound-mediated ligand-exchange strategy based density functional theory calculations, in which compounds possess switchable bonding energy when they transfer between ionized state non-ionized state, hence catalyzing process. By using an...
