{"product_id":"grove-gold-pvp-blue","title":"Grove Gold-PVP Blue \u003c220 nm","description":"\u003cp\u003eAnisotropic gold platelets (\u0026lt;220 nm across) with a polyvinylpyrrolidone (PVP) surface, dispersed in water. The absorption peak is at ~580 nm and the band stays broad into the red: in Grove's example spectrum, absorbance at 633 nm is ~95% of the peak value, and ~50% at 785 nm.\u003c\/p\u003e\n\u003cp\u003eThat makes it a good starting point for SERS and plasmonic sensing with 633 nm excitation. Grove lists SERS substrate development, plasmonic sensing, optical coupling, morphology-dependent optics, and catalysis and electrocatalysis as research uses.\u003c\/p\u003e","brand":"Grove Nanomaterials","offers":[{"title":"10 mL at OD 1","offer_id":55481944867158,"sku":"GROVE-PVP-BLUE-10ML-OD1","price":199.5,"currency_code":"GBP","in_stock":true},{"title":"50 mL at OD 1","offer_id":55507209453910,"sku":"GROVE-PVP-BLUE-50ML-OD1","price":749.0,"currency_code":"GBP","in_stock":true},{"title":"100 mL at OD 1","offer_id":55507209486678,"sku":"GROVE-PVP-BLUE-100ML-OD1","price":1399.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/2802\/2614\/files\/grove-gold-pvp-blue-vial-v3.png?v=1790634740","url":"https:\/\/marixiascientific.com\/products\/grove-gold-pvp-blue","provider":"Marixia Scientific","version":"1.0","type":"link"}
