When nanoparticle conjugation and protein labeling require a well-defined nanoparticle reagent, the 70 nm carboxyl-PEG Gold NanoUrchins format helps procurement and lab teams identify the relevant material and functional configuration.
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 carboxyl-functionalized surface is used for covalent bioconjugation strategies, including protein or ligand coupling where the product data supports conjugation workflows. It provides a chemically addressable nanoparticle surface for preparing custom probes.
The separate specification fields should be used for exact concentration, particle count, optical density, formulation and storage values. This description focuses on product identity, application relevance and selection guidance.
The application profile includes nanoparticle conjugation and protein labeling. 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.
