Product Features
The gold nanorods provided by Xianfeng Nano are prepared by seed growth method and have different absorption peaks to choose from.
Easy to control optical properties:
It has two plasmon resonance absorption peaks, one in the transverse direction and one in the longitudinal direction, giving it a unique optical response. The optical properties of gold nanorods are easier to control and can be achieved by changing their aspect ratio and other parameters.
High surface electric field strength enhancement effect: When gold nanorods are excited by SPR, the surface electric field strength can be enhanced by up to 10 ^ 7 times. This enhancement effect is very useful in fields such as surface enhanced Raman scattering (SERS) and photothermal conversion.
Great optical absorption and scattering cross section: Gold nanorods have a large optical absorption and scattering cross section, which makes them highly sensitive in biosensing and imaging.
Photothermal conversion efficiency: Gold nanorods have a continuously adjustable photothermal conversion efficiency from 50% to 100%, making them effective photothermal conversion agents in photothermal therapy.
Chemical stability: Gold nanorods inherit the chemical stability of gold, which gives them a longer storage time and lifespan in biological applications.
Easy surface modification: The surface of gold nanorods can be modified to enhance their stability and targeting in vivo, which is crucial for applications such as drug delivery and biological imaging.
Controllable morphology and structure: Gold nanorods exhibit a rod-shaped structure, and their length and width can be continuously adjusted within a certain range. By controlling the synthesis conditions, gold nanorods of different sizes and shapes can be obtained.
High index crystal surface: The surface of gold nanorods stabilized by surfactants in water can exhibit high index crystal surfaces, which have high chemical activity and are very useful in catalytic reactions.
Application Fields
biomedical science:
In vitro diagnosis: A biosensor developed based on the surface plasmon resonance properties of gold nanorods, which can be used for in vitro diagnosis in biomedical applications;
In vivo imaging: Gold nanorods have strong scattering of light in the near-infrared band, while the scattering background of living organisms in this band is weak, which makes them suitable as contrast agents for biological imaging based on light scattering;
In vivo therapy: Gold nanorods can circulate and transport within living organisms for up to 15 hours, killing cancer cells with minimal light exposure through photothermal therapy.
In the field of catalysis, gold nanorods coated with palladium or platinum exhibit higher catalytic activity and better stability than pure palladium or platinum catalysts with the same dosage.
Sensor:
Surface enhanced Raman scattering: monodisperse or coupled gold nanorods have extremely strong surface electric field enhancement effects and can be used as Raman enhancers in surface enhanced Raman scattering applications;
Micro molecule detection based on refractive index sensitivity: The refractive index change of the surrounding medium of gold nanorods will cause a red shift in their surface plasmon resonance peaks, which can be used for the detection of trace molecules;
Micro molecule and ion detection based on nanoparticle assembly: Under the action of certain specific molecules or ions, gold nanorods will assemble or aggregate in an ordered or disordered manner, causing changes in their characteristic spectra, which can be used to detect the presence of these specific molecules or ions.
