英文摘要: Adopt double fine emulsion polymerization, the morphology rules, the preparation of magnetic response is good, with surface of carboxyl functional groups of magnetic polymer microsphere. To polyether drugs molecule structure transform, preparation half an antigen, and OVA or BSA connection, to form a completely antigen, immune animals, preparation of monoclonal antibodies. Preparation organic silicon doped phenanthroline ruthenium compound, inorganic silicon coated with the combination of double structure fluorescence silica microspheres nano. Use of magnetic nanoparticles spheres carboxyl surface with antibody surface amino reaction, make magnetic nanoparticles microspheres connected with antibody preparation immune magnetic nanoparticles microspheres; Using fluorescence microspheres surface active functional group (carboxylic), use lively ester method will veterinary medicine monoclonal antibody accidentally united microspheres surface, preparation immunofluorescence microspheres. To get immune magnetic nanoparticles microsphere and immunofluorescence micro ball purification and the nature of the study, with magnetic microsphere as separation carrier, fluorescence microspheres as probes, a biological samples for drug residue detection of fluorescence immune detection method, and the actual samples for testing.
