{"product_id":"15nm-biotin-gold-nanoparticles","title":"15nm Biotin Gold Nanoparticles","description":"\u003cp\u003eFor laboratories developing streptavidin binding and assay development, the 15 nm biotin-functionalized gold nanoparticles format provides a defined material option for online scientific purchasing and product selection.\u003c\/p\u003e\n\u003cp\u003eGold 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 522 nm can help compare this size with related gold nanoparticle options.\u003c\/p\u003e\n\u003cp\u003eBiotin functionalization supports streptavidin binding and biotin-streptavidin assay design. This surface is useful when the experiment depends on modular attachment of streptavidin-labeled or streptavidin-binding components.\u003c\/p\u003e\n\u003cp\u003eThe supplied description notes controlled particle sizing and dynamic light scattering assessment of size and monodispersity. That context is useful for assays where optical response, conjugate behavior or particle-size comparisons need to be reproducible.\u003c\/p\u003e\n\u003cp\u003eThe application profile includes streptavidin binding and assay development. These terms reflect the supported scientific workflows for this listing and help scientists compare related products by use case, not by material alone.\u003c\/p\u003e\n\u003cp\u003eThis size range is often selected as a balance between particle number, optical response and biomolecular surface area.\u003c\/p\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\u003cp\u003eFor 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.\u003c\/p\u003e\n\u003ch3\u003eApplication areas\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eStreptavidin binding and biotin-streptavidin assay development\u003c\/li\u003e\n  \u003cli\u003eAssay development and comparison of nanoparticle size or surface chemistry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cytodiagnostics","offers":[{"title":"0.5 ml","offer_id":58053236588889,"sku":"CGB5K-15-25","price":255.0,"currency_code":"EUR","in_stock":true},{"title":"1 ml","offer_id":58053236621657,"sku":"CGB5K-15-50","price":445.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/1011\/0553\/files\/5nm-functionalized-gold-nanoparticles_ff916173-bad3-47b8-98a6-bd305ff53391.jpg?v=1778675315","url":"https:\/\/absource.de\/products\/15nm-biotin-gold-nanoparticles","provider":"Absource Diagnostics","version":"1.0","type":"link"}
