DiagNanoTM 荧光二氧化硅颗粒是以空白二氧化硅颗粒为基质,将荧光染料共价交联于二氧化硅基质内部而制得的,能有效地防止了荧光染料分子的泄漏。DiagNanoTM 荧光二氧化硅颗粒表现较强的光敏感性、高度光稳定性,良好的表面化学活性和生物亲和性。Si-OH末端的二氧化硅颗粒具有亲水性的表面,很高的化学活性,在有机溶剂和水溶液介质中长期稳定。二氧化硅颗粒表面大量的羟基,可以引入不同的有机官能团,如COOH和NH2等,使其表面功能化,用于偶联蛋白、核酸、抗体等生物分子,建立荧光纳米探针,应用于药物载体,生物标记和生物成像等领域。

本系列产品可提供红色荧光二氧化硅颗粒,绿色荧光二氧化硅颗粒和蓝色荧光二氧化硅颗粒。高度单分散的无孔的二氧化硅,粒径分布在10 nm – 1.5 µm范围内,密度2.0 g/cm³。多孔二氧化硅颗粒,粒径可在3 µm – 20 µm范围内调控,密度1.8 g/cm³。
