Gold Nanocubes
Overview
Gold Nanocubes are a specialized form of gold nanoparticles with a cubic morphology, engineered for their unique plasmonic and catalytic properties. Unlike spherical nanoparticles, their sharp edges and corners enhance localized electric fields, making them ideal for surface-enhanced spectroscopy and photothermal applications. These nanoparticles are typically synthesized via seed-mediated growth methods, allowing precise control over size (10-200 nm) and surface chemistry. Their optical properties, such as strong absorption in the near-infrared (NIR) region, are tunable by adjusting dimensions, enabling customization for specific industrial or biomedical uses.
Physical and Chemical Properties
Gold Nanocubes exhibit distinct physical properties due to their geometry. Their cubic shape results in high surface area and enhanced plasmonic effects compared to spherical counterparts. The localized surface plasmon resonance (LSPR) peaks can be tuned between 500-1200 nm, depending on size and environment. Chemically, they are inert under standard conditions but can be functionalized with thiols, polymers, or biomolecules for targeted applications. Their catalytic activity, particularly in oxidation reactions, is leveraged in industrial processes. Stability in colloidal form depends on surface coatings to prevent aggregation.
Main Applications
In biomedicine, Gold Nanocubes are used for photothermal therapy, where their NIR absorption converts light to heat to destroy cancer cells. They also serve as contrast agents in dark-field microscopy and optical coherence tomography. In electronics, they are integrated into conductive inks and plasmonic circuits. Their catalytic properties are exploited in fuel cells and environmental remediation, such as pollutant degradation. Additionally, they function as substrates for surface-enhanced Raman spectroscopy (SERS), enabling ultra-sensitive molecular detection.
Safety and Storage
While gold is biocompatible, nanocubes require careful handling due to their nanoscale dimensions. Powder forms may pose inhalation risks, necessitating PPE like masks and gloves. Dispersions should avoid direct sunlight to prevent destabilization. Long-term storage recommendations include keeping suspensions at 4°C with stabilizing agents (e.g., citrate or PEG). Lyophilized powders should be sealed under inert gas to minimize oxidation. Always refer to material safety data sheets (MSDS) for specific guidelines.
B2B Procurement Guide
When sourcing Gold Nanocubes, prioritize suppliers providing detailed characterization data, including TEM images for size verification and UV-Vis spectra for LSPR profiles. Key metrics are size uniformity (±5% deviation) and surface functionalization (e.g., PEGylation for biomedical use). Bulk orders (grams) may qualify for discounts, but confirm batch consistency. For research-scale purchases, opt for vials with pre-dispersion in buffers. Lead times vary; custom syntheses (e.g., antibody conjugation) may require 4-6 weeks. Validate supplier certifications (ISO 9001) and request samples for pilot testing.
