Silica Nanoparticles

Monodisperse nanoparticles with available size ranging from 20 to 150 nm. HiQ-Nano Silica Nanoparticles have a hydrophilic surface with terminal Si-OH functional groups and are extremely stable in organic solvents and aqueous buffers.

• Tunable sizes from 20 nm to 150 nm
• Available in water with any surfactants or as dried powder
• Possibility to modulate the surface chemistry:
  • carboxylic acid groups (COOH)
  • amino groups (NH2)
  • sulphonic acid groups (SO3H)
  • thiol groups (SH)
  • hydrophobic trimethylsilyl (TMS) surface
  • hydrophobic trimethylsilyl octadecyl (C18) surface

• Possibility of customized bioconjugation with proteins:
  • Avidin
  • Streptavidin
  • Albumin
  • Transferrin
  • Antibody
  • Enzymes

• Guaranteed-sterility
• ** Endotoxin-free Silica Nanoparticles available upon request
