Its absorption band is the broadest in the range: in Grove's example spectrum, absorbance at 785 nm, the usual near-infrared Raman line, is ~80% of the peak value.\u003c\/p\u003e\n\u003cp\u003eChoose it over Gold-PVP Blue when you need a PEG surface. PEG is widely used to reduce non-specific protein adsorption in biological media; how well it does so depends on how densely it covers the particles, so test it in your own medium. Grove lists plasmonic sensing, nanoparticle assembly and polymer-mediated interfaces as research uses.\u003c\/p\u003e","brand":"Grove Nanomaterials","offers":[{"title":"10 mL at OD 1","offer_id":55481945882966,"sku":"GROVE-PEG-BLUE-10ML-OD1","price":199.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1066\/2802\/2614\/files\/grove-gold-peg-blue-vial-v3.png?v=1790634769","url":"https:\/\/marixiascientific.com\/products\/grove-gold-peg-blue","provider":"Marixia Scientific","version":"1.0","type":"link"}
