Fluorescent Silica Nanobeads from Merck

In comparison to their organic counterparts, inorganic nanoparticles exhibit non-toxicity, biocompatibility, hydrophilicity and exceptional stability. Merck offers a wide array of inorganic nanoparticles, including silica, fluorescent, and nanodiamond varieties, all designed to elevate the scope and quality of your research.

  • Silica products: Available in various modifications tailored to meet research requirements. The company offers ultra-stable fluorescence, mesoporous, non-porous, or functionalized surfaces in a diverse range of sizes for selection.
  • Fluorescent nanoparticles, including conjugated polymer nanoparticles. These are characterized by a semiconductor light-emitting polymer (LEP) core, which is encapsulated within a biocompatible surfactant. Their enhanced stability makes them ideal for multi-modal Magnetic Resonance Imaging (MRI), particularly in cellular imaging applications.


The utilization of labeling or staining agents has significantly advanced the exploration of intricate biological interactions in the field of biology. The fluorescent labeling of biomolecules has proven to be an indispensable tool in numerous biological studies.

Silica nanobeads, owing to their outstanding fluorescence properties, play a crucial role in various applications, including biological labeling, bioimaging, and biosensing.
