Organic Dye Labeled Luminescent Silica Nanoparticles

  • manufactured by sol-gel method
  • diameter range 40 – 900 nm as monodisperse (polydispersity 3 – 12%) and non-porous particles
  • doping with different organic dyes
  • hydrophilic surface with terminal Si-OH groups
  • stable in organic medium and aqueous buffers
  • separation through sedimentation or centrifugation
  • different surface functionalities (e. g. -OH, -SH, -NH2, -COOH) for the covalent bonding of proteins, antibodies or other molecules
  • manufactured with covalent bonded antibodies or proteins (e. g. streptavidin)
