Abstract
本发明公开了一种磁标记生物传感器,其生物探针固定层由导电层、绝缘层以及供电装置构成,绝缘层表面嵌入着多个导电单元,每个导电单元与导电层形成电连接,多个导电单元形成导电单元阵列;当供电装置供电时,经磁标记的生物探针被固定吸附在导电单元阵列表面;检测完毕后,只需停止供电,磁标记的生物探针将即刻脱离导电单元阵列,然后通过清洗处理便能够彻底清除该磁标记的生物探针。因此,本发明避免了现有技术采用化学偶联方法固定生物探针所产生的检测完毕后不能有效清除磁标记的生物探针,从而影响芯片重复利用的问题,同时能够保持现有的检测精度,是一种结构简单、使用方便、可重复利用的新型磁标记生物传感器,具有潜在的应用价值
