MICROESFERAS MAGNETIZAVEIS A BASE DE POLISSILSESQUIOXANO, PROCESSO PARA A SUA PREPARACAO E SUA APLICACAO EM BIOLOGIA |
摘要 |
Magnetisable microspheres consisting of a polysilsesquioxane lattice and distributed uniformly inside the lattice of magnetisable fillers chemically bonded to polysilsesquioxane units. …<??>They are prepared by dispersion in a solvent of an aqueous suspension of magnetisable fillers not coated with dispersing agent, dissolving an alkoxysilane or an alkoxysiloxane in the organic phase, polycondensation to a polysilsesquioxane, removal of water, separation and optional redispersion of the microspheres in water. |
