摘要
采用超细r-Fe2O3粉界表面进行处理,利用苯乙烯、二乙烯基苯单体,采用悬浮聚合法和超声波技术,可以合成粒径为1μm左右的磁性微珠,该磁性微珠由超细磁粉、高分子材料和单抗功能基团组成。结果表明,磁性微珠具有很强耐酸碱性,可以作为蛋白吸附能力的聚合物磁性粒子。用于免疫学检测时的特异性、精密度、重复性、准确性均符合质量控制要求。
The magnetic microbeads with 1 μm diameter were synthesized by uhrafined γ-Fe2O3,cinnamene,diethylene benzene moncase combined suspend polymerize and ultrasonic technology. The magnetic are composcd of ultrafine magnetic powders, polymer and single antibody. The results showed thai magnetic mierobcads can be used as strong capacity for binding protein on the good resistance to acid and alkali. These magnenetic microbeads presen Key words：
