Designed for nanoparticle conjugation and protein labeling, the 90 nm carboxyl-PEG gold nanoparticles format gives researchers a clear starting point when matching nanoparticle material, size and surface chemistry to an experimental workflow.
Gold nanoparticles are widely used as plasmonic labels and conjugation scaffolds because their optical response, surface chemistry and particle size can be matched to assay, imaging or sensor formats. The listed absorption maximum of 564 nm can help compare this size with related gold nanoparticle options.
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 supplied description emphasizes controlled size distribution and defined particle morphology. Those details matter when comparing related nanoparticle products for optical response, conjugation behavior or assay consistency.
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.
For gold nanoparticle workflows, compare standard, stabilized, reactant-free, endotoxin-free and functionalized versions according to the application. The same size can behave differently depending on the surface chemistry and formulation.
For procurement and product selection, compare it with related nanoparticles by particle size, surface chemistry, formulation and listed application rather than treating all nanoparticles as interchangeable.
