二氧化硅顆粒

DiagNano? 二氧化硅顆粒，是以正硅酸乙酯為原料采用Stober法制備的粒徑分布均勻的球形二氧化硅納、微米顆粒，通過調節反應溫度、反應時間和NH₄OH、H₂O和TEOS的濃度，可以調節二氧化硅的粒徑和粒度分布（DLS表征）。單分散的無孔的二氧化硅，粒徑分布在10 nm – 1.5 μm范圍內，密度2.0g/cm3 。多孔二氧化硅顆粒，粒徑可在3 μm – 20 μm范圍內調控，密度1.8 g/cm3。

Si-OH末端的二氧化硅顆粒具有親水性的表面，化學活性，在有機溶劑和水溶液介質中長期穩定。二氧化硅顆粒表面的羥基，可以使多種物質結合到顆粒表面，改善顆粒表面狀態，實現對其化學修飾。可以引入不同的有機官能團，如COOH、NH₂、NHS、Epoxy、Ni-NTA和C18等，使其表面功能化，也可以共價結合多種生物分子，如Streptavidin、Avidin和Protein A等，提高其生物靶向性，應用于生物分析，生化檢測等領域。
