Systems and methods including linked localization agents

Systems and methods are provided that include two or more localization agents linked together by a linker. For example, the present application provides systems and methods for placing two or more linked localization devices within a biological system and detecting such localization devices for targeting a surgical or other medical procedure. For example, this application provides a system comprising one or more micro-detectable devices linked together, which are placed into a target location and activated by remotely introducing a magnetic field. 本申请提供包括通过链接器链接在一起的两个或更多个定位剂的系统和方法。例如，本申请提供用于将两个或更多个链接定位设备放置在生物系统内并且检测此类定位设备以用于靶向手术或其他医疗规程的系统和方法。例如，本申请提供包括链接在一起的一个或多个微型可检测设备的系统，这些微型可检测设备被放置到目标定位中并且通过远程引入磁场来激活。
