Embodiments herein include a scanning apparatus for detecting target particles present within a ferrofluid, where the scanning apparatus can be used in a microfluidic system. The methods and structures described herein also include, for example, a scanning device comprising an optical system, a first magnet disposed on a first side of the optical system, where the first magnet can be non-rotatable, a second magnet disposed on a second side of the optical system, opposite the first magnet, where the second magnet can be rotatable, and a lever arm coupled to the second magnet, where the lever iscapable of rotating the second magnet. 本实施例包括一种用于检测存在于铁磁流体中的目标粒子的扫描装置，其中该扫描装置可以用于微流系统中。此处描述的方法和结构也包括：例如扫描装置，该扫描装置包括光学系统；位于该光学系统的第一侧上的第一磁体，第一磁体可以是不可旋转的；位于该光学系统的第二侧上的第二磁体，与第一磁体相对，第二磁体可以是可旋转的；和活动臂，其连接到第二磁体，臂能使第二磁体旋转。
