High-Purity Gold Nanorods (Au NRs)

 

Anisotropic gold nanoparticles called gold nanorods (Au NRs) have plasmonic activity that can be changed, spanning visible to near-infrared (NIR) wavelengths. Because of their unique optical qualities, they are a popular choice for biomedical imaging, sensing, and photonics research. MKnano provides research-grade gold nanorods to laboratories, universities, and businesses in the US, Canada, and across the world.

Gold Nanorods: Overview

Gold nanorods are one of the most researched anisotropic nanomaterials in nanoscience because they have a plasmonic response that depends on their shape, can be modified on their surface, and are important for biology.

What Are Gold Nanorods?

Gold nanorods are long gold nanoparticles that are characterized by their aspect ratio, which is the ratio of their length to their width. Their anisotropic shape creates two LSPR modes: a transverse band that is around 520 nm wide and a longitudinal band that can be adjusted from 600 nm to over 1000 nm. Changing the aspect ratio gives you exact control over how much light is absorbed for certain uses.

Why Gold Nanorods Matter

  • Strong NIR optical absorption with large extinction coefficients.
  • Tunable LSPR from visible to near-infrared wavelengths.
  • Functionalizing the surface using thiol, PEG, or antibody conjugation.
  • Very good at converting light into heat.
  • Works with imaging, biosensing, and nanophotonic systems.

Applications of Gold Nanorods

  • Drug Delivery and Surface-Conjugated Systems:

    Gold nanorods have a high surface area-to-volume ratio that makes them great carriers.
  • Photothermal Therapy:

    Gold nanorods are able to convert laser light into localized heat, which is used to destroy malignant cells with minimal damage to healthy tissue.
  • Photoacoustic Imaging:

    They absorb short laser pulses to generate ultrasonic waves, enabling deep-tissue imaging.
  • Biosensing and LSPR Detection:

    They help in real-time detection of proteins, pathogens, and chemicals.
  • Nanophotonics and Optical Research:

    Used for Surface-Enhanced Raman Spectroscopy (SERS) and non-linear optical studies.
