Abstract: The subject invention pertains to a novel system capable of long-term monitoring the concentration of a typical analyte in body fluid. The invention includes an untethered battery-free concentration monitor and an external data recorder to continuously measure the concentration of certain analytes and send out signals corresponding to the measured analytes concentration in real-time.

Abstract: An integrated robotic system and methods for delivery and on-demand tasks of magnetic devices in a body for different clinical applications are provided. The integrated robotic system includes a magnetic actuation device, a plurality of imaging devices, a delivery device, and at least one magnetic device. The magnetic actuation device includes a permanent magnet or an electromagnetic coil system, and a controller for controlling the magnetic device. The plurality of imaging devices include two or more imaging modalities for capturing images of the magnetic device and tracking locations of the magnetic device in the body. The magnetic device includes one or more selected from a millimeter-sized robot, a microrobot, a nanorobot, a microrobotic swarm, and particles or drugs that respond to a magnetic field and small enough to be delivered by the delivery device.

Abstract: Magnetic field has been considered as a safe and promising method for remote control of medical robots in body. Systems that implement electromagnetic coils can provide wide control bandwidth and on-off capability. However, scaling-up the working space of such systems for clinical use and increasing energy efficiency to reduce heat generation have always been a challenging task. The design, modeling and control methods for a magnetic actuation system with multiple mobile electromagnetic coils with decoupled movements are introduced. The high flexibility of such configuration and the proposed real-time control strategy enables the system to enlarge the working space by tracking the locomotion of the robot, deal with the irregularly shaped obstructions inside the working area, work with medical imaging systems for localization of the medical robots, generate various kind of magnetic field for actuation and conduct real-time optimization on coils' positions to enhance energy efficiency.

Abstract: Disclosed are materials, devices, methods and systems for the detection of target molecules in test samples using microrobots. The target molecules may be bacterial toxins. The microrobots may include biohybrid materials such as porous spore core, a middle layer coated on the spore core for the actuation and steering in a fluid and further conjugation with a functional probe, and a sensing probe anchored onto middle layer for attaching to the targeted molecules in a fluid to respond to fluorescent tracking. A system for detecting bacterial toxin, is disclosed and comprises an intelligent motion control system based on automated fluorescent recognition and detection methods, which can propel and guide the microrobots to realize the automated motion in a pre-designed path and perform the real-time monitoring when integrating with an inverted fluorescent microscope or a fluorescent emission multi-reader.
