Amino coated TiO2 titania nanospheres and microspheres
We are only supplier of truly uniform and monodisperse aminated titania (amino functional groups coated titanium dioxide) microspheres and nanospheres.
Properties of titania microspheres and nanospheres:
Size: nanospheres 100-950nm, microspheres 1-100µm.
Solubility in water: insoluble (weak acid and bases)
Solubility in organic solvents: insoluble.
Density: 2.2g/cm3.
Crystal structure: amorphous (could be converted into crystalline state anatase or rutile by heating).
Surface charge: Amino groups NH2d
Special property: Strong oxidant of organic molecules
Functional surface titania microspheres and nanospheres:
Currently we offer titania microspheres and nanospheres with plain, amino and carboxyl functional groups. The titania microspheres and nanospheres are also available on custom synthesis basis with other functional groups such as albumin, protein A, epoxy, NHS, NTA, EDTA et others. Please ask for delivery time and quotation.
They are useful for coupling of DNA, oligonucleotides, oligopeptides, proteins, lectines and antibodies.
Dyed and fluorescent titania microspheres and nanospheres:
Currently not available
Doped with other elements titania microspheres and nanospheres:
On custom synthesis basis we can dope these microparticles selected other elements with up to 2 %. The doped elements could be distributed uniformly, internally or externally.
