20nm Endotoxin Free Gold Nanoparticles

When nanoparticle conjugation, toxicity studies, immunological studies, and aseptic assay workflows require a well-defined nanoparticle reagent, the 20 nm endotoxin-free gold nanoparticles format helps procurement and lab teams identify the relevant material and functional configuration.

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 524 nm can help compare this size with related gold nanoparticle options.

The endotoxin-free format is selected for toxicity studies, immunological studies and aseptic assay workflows where the listed product data supports attention to endotoxin burden. It remains a nanoparticle reagent for scientific experiments, not a broad-purpose substitute for other surface chemistries.

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, toxicity studies, immunological studies, and aseptic assay workflows. 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 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.

Application areas

• Nanoparticle conjugation with supported proteins, ligands or biomolecules
• Toxicity, nanotoxicology or exposure-response studies where listed
