General description

  • Longitudinal peak = 550 nm (± 20 nm)
  • Longitudinal absorbance OD = 1
  • Transverse peak = 525 nm (± 5 nm)
  • Transverse absorbance OD = 0.9

Application

Owing to the excellent optical properties arising from the surface plasmon resonance, the gold nanorods find applications in biomedical imaging, drug delivery and photothermal treatment. The citrate capped nanorods are non-cytotoxic compared to the CTAB capped nanorods and are well suited for the biomedical applications.

Caution

Do not freeze.
Keep container tightly closed in a dry and well-ventilated place.
Recommended storage temperature 2-8 C.

Gold nanoparticles are chemically fabricated and tuned to strongly absorb near infrared (NIR) light, enabling deep optical penetration and therapy within human tissues, where sufficient heating induces tumour necrosis. In our studies we aim to establish the optimal gold nanorod

Photothermal therapy, also referred to as optical hyperthermia or photothermal ablation, is an emerging strategy for treating solid tumours. Colloidal gold converts the absorbed light into localized heat via a non-radiative mechanism, surface plasmon resonance, which ablates the solid tumours.
