Technical Properties:

Applications:

• Biomedical and Healthcare Applications: Gold nanoparticles serve as contrast agents in CT and photoacoustic imaging, carriers for targeted drug delivery, and mediators of photothermal/photodynamic tumor ablation. Their antimicrobial coatings on implants and dressings also curb biofilm formation and support wound healing.
• Electronics and Conductive Materials: AuNPs formulate conductive inks for printed and flexible circuits, enable surface-enhanced Raman sensors for chemical/biological detection, and form low-resistance contacts in nanoelectronic devices.
• Chemical and Catalytic Applications: As heterogeneous catalysts, AuNPs drive the selective oxidation of alcohols, reduction of nitroarenes, and low-temperature CO oxidation. In electrocatalysis, they improve CO₂ reduction and oxygen-reduction reactions in fuel cells.
• Agriculture and Food Safety: Functionalized AuNPs power colorimetric or electrochemical strips that rapidly detect pesticides, mycotoxins, and pathogens, while AuNP-embedded smart packaging signals spoilage and gas emissions.
• Environmental and Filtration Systems: AuNP-based SERS sensors identify heavy metals and organics at parts-per-billion levels. Incorporated into membranes or adsorbents, they catalyze pollutant degradation under light and selectively remove arsenic and mercury.
