Abstract Plasmonic gold nanorods (Au NRs)–copper sulfide heterostructures have recently attracted much attention owing to the synergistically enhanced photothermal properties. However, facile synthesis and interface tailoring of Au NRs–copper remain a formidable challenge. In this study, rational design NRs–Cu 7 S 4 via one‐pot hydrothermal process is reported. Specifically, core–shell dumbbell‐like are obtained with well‐controlled interfaces by employing NRs different aspect ratios. Both...

The combination of noble metal and oxide support is a good approach to reduce the cost catalyst improve stability nanocatalyst in chemical reactions. Here, metal/zinc composites, including Pd/ZnO Pt/ZnO, have been facilely prepared through general one-pot hydrothermal method. Importantly, morphology composites can be tuned from tube, flower, star skin needling-like shapes by easily adjusting alkalinity reaction solution. By investigating growth mechanism influencing factors differences...

The aim of this study is to elucidate the impact surface charge glycerol monooleate-based nanoparticles (NPs) on cellular uptake and its distribution in cochlea. These NPs are modified using varied concentration anionic or cationic lipid. Upon dilution, these lipid mixtures self-assemble form a series cubic with various charges, but similar particle size. Positively charged exhibited dose-dependent cytotoxicities against L929 cells proportional lipid; whereas negatively did not show obvious...

Bifunctional heterostructures composed of gold nanorods and hematite nanoparticle aggregates are prepared facilely through the hydrothermal decomposition ferric acetylacetonate on surface nanorods.

An approach for the transverse oxidation of Au nanorods has been demonstrated by selectively capping ends with Ag2O through a hydrothermal reaction. The tight protects and restricts to occurring only at side surfaces. Such leads gradual reduction in effective diameter nanorods, an increase aspect ratio, therefore red shift longitudinal plasmon resonance. resonance can reach up 250 nm be controlled varying time. In addition, process is also applicable different wavelengths. Furthermore,...
