Product Features
Surface Plasmon Resonance (SPR): Gold nanorods exhibit strong surface plasmon resonance properties, which give them special optical absorption and scattering characteristics in the visible to near-infrared region. Adjustable optical properties: By changing the size and shape of gold nanorods, especially their aspect ratio, the position of their SPR peak can be adjusted, achieving control over the absorption and scattering characteristics of light. Sodium citrate modification: Sodium citrate, as a reducing agent and stabilizer, is used in the synthesis process of gold nanorods to help control their growth and provide surface modification, increasing their stability in aqueous media. Biocompatibility: Sodium citrate modified gold nanorods exhibit excellent biocompatibility, making them suitable for biomedical applications such as photothermal therapy, drug delivery, and bioimaging. Easy to functionalize: The surface of gold nanorods can be further modified by covalently or non covalently connecting specific biomolecules, such as antibodies, proteins, or nucleic acids, to achieve targeted therapy or specific detection. Photothermal conversion efficiency: Gold nanorods can effectively convert light energy into heat energy under near-infrared light irradiation, therefore they have potential applications in photothermal therapy. Catalytic activity: The surface of gold nanorods has catalytic activity and can be used as catalysts or catalyst carriers for various chemical reactions.
Application Fields
Biosensing: The surface plasmon resonance properties of gold nanorods give them potential applications in the construction of biosensors for detecting trace molecules. Biological imaging: Gold nanorods have strong scattering in the near-infrared band and can be used as contrast agents for biological imaging, especially in light scattering imaging. In vivo therapy: Gold nanorods can be used for photothermal therapy, utilizing their absorption of near-infrared light to convert it into heat energy to treat diseases, such as killing cancer cells. Catalysis: Gold nanorods can serve as catalysts or catalyst carriers to improve the efficiency of catalytic reactions, especially under conditions of light irradiation. Sensors: The surface enhanced Raman scattering (SERS) effect of gold nanorods makes them applicable in the field of sensors for detecting biomolecules, ions, etc.
