40nm Silver Nanoparticles

Designed for biosensing, toxicity studies, multiplex assay development, and photovoltaic studies, the 40 nm silver nanoparticles format gives researchers a clear starting point when matching nanoparticle material, size and surface chemistry to an experimental workflow.

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 citrate-stabilized silver format is suited to colloidal silver workflows where optical response, particle size and formulation are the main selection variables. It should be compared with functionalized silver products when binding chemistry is required.

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 biosensing, toxicity studies, multiplex assay development, and photovoltaic studies. These terms reflect the supported scientific workflows for this listing and help scientists compare related products by use case, not by material alone.

This size range is often selected as a balance between particle number, optical response and biomolecular surface area.

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

• Biosensing and optical sensor development
• Toxicity, nanotoxicology or exposure-response studies where listed
• Multiplex assay development using distinct optical nanoparticle signals
• Photovoltaic or materials-science studies where silver nanoparticles are specified
