{"product_id":"silver-nanocube-colloid","title":"silver nanocube colloid","description":"\u003cp\u003eProduct Name silver nanocube colloid Product Overview This product (Code: XFJ293) is a monodisperse silver nanocube colloid modified with PVP, using absolute ethanol as the dispersion solvent. It features regular morphology, uniform size, and no spherical or irregular impurity particles. Prepared by precise liquid-phase synthesis technology, the product is coated with a polyvinylpyrrolidone (PVP) protective modification layer and presents negative surface charge with excellent colloidal system stability, avoiding sedimentation and agglomeration during long-term storage. The liquid appears yellow-green macroscopically with a characteristic UV absorption peak at about 460 nm. It possesses typical and excellent localized surface plasmon resonance (LSPR) effect, serving as a core scientific research and industrial raw material for surface-enhanced Raman scattering, optical sensing, optoelectronic thin films, catalysis, and antibacterial materials. Technical Parameter Particle Size :\u0026lt;100 nm Surface Modifier :PVP Surface Charge: Negative Charge Solution Color :Yellow-green Characteristic Absorption Peak: 460 nm(UV-Vis) Product Features • Regular Morphology and Excellent Monodispersity: The product adopts a standard cubic nanostructure with particle size strictly controlled within 100 nm, no irregular particles or agglomeration, and high particle uniformity, which ensures the repeatability of experimental data and the consistency of device preparation. • Stable PVP Modification and Wide System Compatibility: The uniform and stable PVP modification layer on the surface effectively prevents particle agglomeration and sedimentation through steric hindrance effect. The negative surface charge is compatible with most substrates and liquid phase systems, and can be directly used in doping, coating, assembly and other processes without complicated pretreatment. • Stable and Controllable Plasma Performance: The precisely controlled particle size and cubic structure enable the product to have a stable characteristic absorption peak at 460 nm, excellent LSPR response performance, uniform optical signal and high sensitivity, suitable for various optical sensing and spectral detection scenarios. • Wide Compatibility of Ethanol System: Using absolute ethanol as the dispersion medium, it has low volatile residue and better compatibility than water-based dispersion liquid. It is suitable for hydrophobic substrates, organic system composite, low-temperature coating and other scenarios, adapting to more material preparation processes. Accurate Concentration and Stable Batch Performance: The factory concentration is accurately fixed at 0.1 mg\/mL with 10 mL quantitative packaging. The parameter deviation between batches is extremely small, and the colloid has strong long-term storage stability, which greatly reduces experimental errors. Application Fields • Surface-Enhanced Raman Scattering (SERS) Substrate: The unique cubic angular structure of silver nanocubes can produce extremely strong electromagnetic field enhancement effect. The 460 nm plasma resonance absorption is suitable for visible light excitation, making it a high-quality substrate material for high-sensitivity SERS detection, trace substance analysis and biomolecular detection. • Optical Sensing and Detection Devices: Relying on stable LSPR optical properties, it is used for the R\u0026amp;D and preparation of optical sensors, refractive index sensing, gas detection, biosensing and other devices, with the advantages of fast response speed and high detection accuracy. Preparation of Optoelectronic Functional Thin Films: The ethanol dispersion system is compatible with solution spin coating, spraying and dipping coating processes, and can prepare high-conductivity and high-light-transmittance nano-silver thin films, which are applied in flexible electronics, transparent electrodes, optoelectronic devices and other fields. • Nano Catalytic Materials: The regular cubic single crystal structure has controllable specific surface area and abundant surface active sites, which can be used in scientific research experiments and applied research of organic catalysis, photocatalysis and environmental degradation catalysis. • Antibacterial Composite Materials: Nano-silver has excellent broad-spectrum antibacterial properties, and can be doped to prepare antibacterial coatings, textile composite materials and medical antibacterial materials, widely used in environmental protection, medical and daily new material fields. • Modification of Nanocomposites: It is used for doping modification of polymer materials and organic thin films to improve the comprehensive electrical conductivity, thermal conductivity, optical and antibacterial properties of materials.
