80nm Carboxylated (carboxyl-PEG5000-SH) Silver Nanoparticles

For laboratories developing nanoparticle conjugation and protein labeling, the 80 nm carboxyl-PEG silver nanoparticles format provides a defined material option for online scientific purchasing and product selection.

Silver nanoparticles provide a plasmonic alternative to gold nanoparticles, with optical behavior useful for biosensing, multiplex assay development and materials-oriented studies where those applications are listed in the product data.

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.

For silver nanoparticle workflows, compare citrate, biotin, carboxyl and methoxy-PEG formats according to whether the experiment needs optical signal, covalent coupling, streptavidin binding or reduced non-specific binding.

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.

Application areas

• Nanoparticle conjugation with supported proteins, ligands or biomolecules
• Protein labeling and protein-nanoparticle conjugate preparation
