Carboxyl coated Al2O3 alumina nanospheres and microspheres
    We are only supplier of truly uniform and monodisperse carboxylated alumina ( carboxyl functional groups coated aluminum oxide) microspheres and nanospheres.
     
    Properties of alumina microspheres and
    nanospheres  :

    Size : nanospheres 100-950 nm, microspheres 1-100 µm.
    Solubility in water : insoluble
    Solubility in organic solvents : insoluble.
    Density : 2.2 g/cm3.
    Crystal structure : amorphous  (could be converted into crystalline state by heating).
    Surface charge : Carboxyl groups COOH
     
    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.
