Preparation method for fluorescent western-blotting magnetic composite microballoon
Publication date: 2015
The invention belongs to the field of material science and engineering and bioseparation engineering, and concretely relates to a preparation method for a fluorescent western-blotting magnetic composite microballoon. A miniemulsion polymerization method is employed to take phycocyanin as a molecular imprinting template and combine with a magnetically-sensitive fluorescent material, so that the phycocyanin molecular-imprinted-polymer magnetic fluorescent composite microballoon is obtained. By using the miniemulsion polymerization method, the molecular-imprinted-polymer microballoon integrates the magnetic and fluorescence double-responsive material, has specific recognition and autonomous adsorption on phycocyanin, is good in selectivity, high in adsorption efficiency, fast in speed, convenient and rapid for separation under the effect of an external magnetic field, and good in repeated usage performance, and is capable of realizing fluorescence real-time detection and fluorescence imaging at a relatively wide pH scope. Also the obtained magnetic core-shell blotting microballoon is regular in morphology and uniform in particle size. The preparation method has the advantages of low cost, simple and convenient operation, good reappearance and the like, and has wide application prospect.
