100nm Gold NanoUrchins

Designed for surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR), nanoparticle conjugation, and lateral flow assay development, the 100 nm Gold NanoUrchins format gives researchers a clear starting point when matching nanoparticle material, size and surface chemistry to an experimental workflow.

Gold NanoUrchins use a spiky gold morphology rather than a smooth spherical surface. This uneven surface is relevant to plasmonic workflows because it is associated with far-red optical absorption and enhanced electromagnetic fields at protrusions, which supports SERS and LSPR applications when those are listed.

The citrate-stabilized colloidal format is commonly used for passive adsorption of proteins and other ligands to the nanoparticle surface. It is well aligned with assay development, lateral flow, immunoassay and electron microscopy workflows when those applications are listed.

The supplied description notes controlled particle sizing and dynamic light scattering assessment of size and monodispersity. That context is useful for assays where optical response, conjugate behavior or particle-size comparisons need to be reproducible.

The application profile includes surface-enhanced Raman spectroscopy (SERS), localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, immunoassay development, and electron microscopy. These terms reflect the supported scientific workflows for this listing and help scientists compare related products by use case, not by material alone.

This mid-to-large nanoparticle size can be useful when stronger optical contrast or more particle surface area is desired. Compared with smooth spherical gold nanoparticles, Gold NanoUrchins should be selected when the spiky morphology and supported SERS or LSPR application profile are relevant.

For Gold NanoUrchin workflows, compare unmodified, biotin, carboxyl and methoxy-PEG versions according to whether the assay needs plasmonic signal, streptavidin binding, covalent coupling or a reduced-binding control surface.

For procurement and product selection, compare this item with related entries by material, size, surface chemistry, formulation and the application terms shown in the product data rather than by product name alone.
