100nm Biotin Gold NanoUrchins

For assay teams comparing nanoparticle options for streptavidin binding, lateral flow assay development, immunoassay development, and electron microscopy, the 100 nm biotin-functionalized Gold NanoUrchins format keeps selection focused on particle material, size, shape and chemistry.

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.

Biotin functionalization supports streptavidin binding and biotin-streptavidin assay design. This surface is useful when the experiment depends on modular attachment of streptavidin-labeled or streptavidin-binding components.

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 streptavidin binding, lateral flow assay development, immunoassay development, electron microscopy, and assay development. 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.
