Product Name

Name: Gold Nanobipyramids

Product Overview

Gold nanobipyramids are nanostructures of precious metal gold with unique geometric shapes and surface plasmon resonance properties. They usually consist of double hexagonal pyramids with a common base, exhibit anisotropy, and can exhibit significant longitudinal surface plasmon resonance properties in the visible to infrared spectrum. These properties of gold nanobipyramids make them potentially useful in fields such as optical sensing, surface-enhanced Raman scattering (SERS), and photothermal conversion therapy.

Technical Parameter

Appearance:Tea-colored dispersion

Length:0-85 nm

Diameter:0-35nm

Product Features

Surface plasmon resonance (SPR): Due to its size and shape, gold nanobipyramids exhibit strong surface plasmon resonance effects, especially with significant resonance absorption peaks in the longitudinal direction (along the long axis of the bipyramids).

Polarization dependence: The SPR effect of gold nanobipyramids shows obvious polarization dependence, that is, their optical properties change according to the polarization direction of the incident light.

High local field enhancement: The tip and edge regions of gold nanobipyramids can produce high local electromagnetic field enhancement, which is very important for applications such as surface-enhanced Raman scattering (SERS) and photocatalysis.

Biocompatibility: Gold nanobipyramids generally have good biocompatibility, making them suitable for biomedical applications such as drug delivery, biosensing, and photothermal therapy.

Application Fields

Surface Enhanced Raman Scattering (SERS):Gold nanobipyramids have important applications in the preparation of SERS detection substrates due to their surface plasmon resonance properties.

Biosensing and photothermal therapy:The surface plasmon resonance characteristics of gold nanobipyramids are significantly better than those of gold nanorods of corresponding sizes, so they have broad potential applications in biosensing, photothermal therapy, and in vivo SERS detection.
