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.
