DiagNano™ silica particles are available with NH₂, COOH, epoxy, NR₃⁺, NHS, NTA, Ni-NTA and EDTA groups on the surface in the size range from 30 nm to 20 µm. The NH2, COOH and epoxy functionalized particles are ideal for covalent binding of proteins, antibodies or other target molecules. Epoxy functionalized particles allow direct binding with biomolecules in a conjugation buffer at pH=9 for conjugation with amine groups, or at pH=7 for reaction with SH groups. DiagNano™ silica particles are also available with nickel(II) chelator nitrilotriacetic acid (NTA) and metal ions chelator EDTA on the surface in the size range of 300 nm to 20 µm. NTA or corresponding nickel complex (Ni-NTA) functionalized particles are designed for the binding of histidine labeled proteins, while EDTA functionalized particles can be applied for the complexation of metal ions Cu²⁺, Ni²⁺, Fe³⁺ and Co³⁺. All these silica particles are supplied in water without any surfactants. We also provide organic silica particles functionalized with acrylate, C18 or trimethylsilyl (TMS), which are provided as powders and allow a direct suspension of the particles in organic solvents.
