Melamine nanospheres and microspheres with amino functional surfaces
    Our melamine nanospheres and microspheres are highly spherical, monodisperse with highest possible density of surface amino groups.    The technology we apply allow us to produce these melamine particles having the density of amino surface groups to one NH or NH2 groups at every nm2.    For example each particle with 1µm diameter will have at least 3,000,000 surface amino groups.
     
    Surface of amino melamine microparticles are terminated with amino groups, which could be used for various conjugation reactions
