DiagNano™ 二氧化硅颗粒，是以正硅酸乙酯为原料采用Stober法制备的粒径分布均匀的球形二氧化硅纳、微米颗粒，通过调节反应温度、反应时间和NH4OH、H2O和TEOS的浓度，可以调节二氧化硅的粒径和粒度分布（DLS表征）。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2.0g/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。
Si-OH末端的二氧化硅颗粒具有亲水性的表面，化学活性，在有机溶剂和水溶液介质中长期稳定。二氧化硅颗粒表面的羟基，可以使多种物质结合到颗粒表面，改善颗粒表面状态，实现对其化学修饰。可以引入不同的有机官能团，如COOH、NH2、NHS、Epoxy、Ni-NTA和C18等，使其表面功能化，也可以共价结合多种生物分子，如Streptavidin、Avidin和Protein A等，提高其生物靶向性，应用于生物分析，生化检测等领域。
