Silica Particles

Silica Particles are monodisperse, high-purity SiO₂ microspheres widely used in biotechnology, diagnostics, material science, and nanotechnology research. These silica microspheres feature controlled size distribution, excellent thermal and chemical stability, and high surface reactivity, making them ideal for bioassays, chromatography, flow cytometry calibration, and surface modification studies. Available as plain, carboxylated, or amine-functionalized silica beads, they enable bioconjugation with antibodies, proteins, and nucleic acids for biosensing, diagnostic assays, and imaging applications. Their optical transparency, low autofluorescence, and strong chemical resistance make silica particles a preferred choice for nanoparticle synthesis, drug delivery research, and fluorescence microscopy.
