We
are only supplier of truly uniform and monodisperse aminated alumina (amino
functional groups coated aluminum
oxide) microspheres and nanospheres.
Properties of alumina
microspheres and nanospheres:
Size: nanospheres 100-950nm, microspheres
1-100µm.
Solubility in water:
insoluble
Solubility in organic solvents: insoluble.
Density: 2.2g/cm3.
Crystal structure:
amorphous (could be converted into crystalline state by heating).
Surface charge: Amino groups NH2
Functional surface
alumina microspheres and nanospheres:
Currently we offer alumina microspheres and nanospheres with
plain, amino
and carboxyl functional groups. The alumina
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
alumina microspheres and nanospheres:
Currently not available
Doped with other elements
alumina 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.
