{"product_id":"20nm-standard-gold-nanoparticles","title":"20nm Standard Gold Nanoparticles","description":"\u003cp\u003eFor assay teams comparing nanoparticle options for localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, and immunoassay development, the 20 nm gold nanoparticles format keeps selection focused on particle material, size, shape and chemistry.\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 524 nm can help compare this size with related gold nanoparticle options.\u003c\/p\u003e\n\u003cp\u003eThe citrate-stabilized colloidal format is commonly used for passive adsorption of proteins and other ligands to the nanoparticle surface. It is well aligned with assay development, lateral flow, immunoassay and electron microscopy workflows when those applications are listed.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eThe application profile includes localized surface plasmon resonance (LSPR), nanoparticle conjugation, lateral flow assay development, immunoassay development, biosensing, and electron microscopy. 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\u003eNanoparticle conjugation with supported proteins, ligands or biomolecules\u003c\/li\u003e\n  \u003cli\u003eLateral flow assay development and rapid-test component optimization\u003c\/li\u003e\n  \u003cli\u003eImmunoassay development, immunostaining or related antibody-based formats\u003c\/li\u003e\n  \u003cli\u003eBiosensing and optical sensor development\u003c\/li\u003e\n  \u003cli\u003eLocalized surface plasmon resonance (LSPR) sensing and optical nanoparticle studies\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Cytodiagnostics","offers":[{"title":"20 ml \/ 1 OD","offer_id":58053255594329,"sku":"G-20-20","price":70.0,"currency_code":"EUR","in_stock":true},{"title":"20 ml \/ 10 OD","offer_id":58053255627097,"sku":"G-20-20-10","price":485.0,"currency_code":"EUR","in_stock":true},{"title":"100 ml \/ 1 OD","offer_id":58053255659865,"sku":"G-20-100","price":235.0,"currency_code":"EUR","in_stock":true},{"title":"100 ml \/ 10 OD","offer_id":58053255692633,"sku":"G-20-100-10","price":1075.0,"currency_code":"EUR","in_stock":true},{"title":"500 ml \/ 1 OD","offer_id":58053255725401,"sku":"G-20-500","price":835.0,"currency_code":"EUR","in_stock":true},{"title":"500 ml \/ 10 OD","offer_id":58053255758169,"sku":"G-20-500-10","price":5375.0,"currency_code":"EUR","in_stock":true},{"title":"1,000 ml \/ 1 OD","offer_id":58053255790937,"sku":"G-20-1000","price":1075.0,"currency_code":"EUR","in_stock":true},{"title":"1,000 ml \/ 10 OD","offer_id":58053255823705,"sku":"G-20-1000-10","price":10750.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/1011\/0553\/files\/15nm-Gold-Nanoparticles_ab09ebe8-f30e-4af9-9719-b0688ad4ea53.jpg?v=1778675484","url":"https:\/\/absource.de\/products\/20nm-standard-gold-nanoparticles","provider":"Absource Diagnostics","version":"1.0","type":"link"}
