生物活性

Silicon dioxide (Silica) is the core of gold-coated silica nanoparticles. Silicon dioxide has the characteristic of a spherical structure, with a layer of gold nanoparticles covering its surface. Silicon dioxide can be used as a coating material for quantum dots, enhancing their stability, reducing toxicity and improving hydrophilicity[1][2].

体外研究
(In Vitro)

Silicon dioxide 制备的纳米颗粒 (SiO₂NPs) 是应用最广泛的纳米材料之一,被广泛用于工业、化妆品和生物医学领域。但 SiO₂NPs 能够通过破坏自噬过程来损害蜕膜化,从而可能导致胚胎吸收[1]
Silicon dioxide 包被的量子点作为一种多功能纳米平台,可作为荧光标记用于体外检测、用于生物分子传感和体内外成像[2]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
