A microelectronic controlled magnetic cleaning system, comprising a micron-scale fine line inner-end part, a micro-scale fine line outer motor control part, and a micro-scale fine line outer system electronic control part. The micron-scale fine line inner-end part is manufactured as a plurality of micron-scale magnetic fine lines, wherein the central magnetic fine lines are slightly wider than the periphery magnetic fine lines. The inner-end part of the central magnetic fine lines is spiral shaped. The micro-scale fine line outer motor control part is made by adding a high-precision micro-motor at the middle portion outside the central magnetic fine lines, When a larger obstruction is found by an endoscope or other optical device imaging system, the central magnetic fine lines can be controlled to arrive at a designated position, and motor speed can be controlled to clean the obstruction. Also disclosed is a micro-electronic controlled magnetic cleaning method.

The present subject matter described herein relates to a Magnetically Augmented Plasmonic Tweezer (MAPT), a method for fabrication of the MAPT, and a method for trapping and maneuvering one or more colloidal particles inside a fluid. The fluid may correspond to a fluid inside a microfluidic device or a biological fluid. The MAPT can comprise a helical support structure to provide maneuverability in fluid. Further, a magnetic component is integrated in the MAPT for motion control. Plasmonic nanostructures are integrated in the MAPT for optical trapping of particles.

A computer-implemented method of internally printing a biostructure on a damaged area of a patient. The method includes: assembling a first bioprinter capsule and a first cartridge capsule to form an assembled bioprinter internally within the patient based, at least in part, on directing one or more magnetic fields towards a first bioprinter capsule and a first cartridge capsule, moving the assembled bioprinter to the internally damaged area of the patient based, at least in part, on altering the one or more external magnetic fields directed towards the assembled bioprinter, and printing, via the assembled bioprinter, a first biostructure onto the internally damaged area of the patient based, at least in part, on altering the one or more external magnetic fields directed towards the assembled bioprinter, wherein the one or more external magnetic fields are sequentially altered to incrementally move the assembled bioprinter along at least one plane.

A wireless magnetic ultrasonic cavitation in-vivo therapeutic robotic device, including a micro-robot and an in-vitro control device; the in-vitro control device has an outer housing in which provided with electromagnetic coils and wireless power emitting coils; the micro-robot has a capsule shaped housing in which a super magnetic module is provided; a micro ultrasonic vibrator and a micro wireless power receiving coil electronically connected with each other are provided inside the housing; the wireless power emitting coils emit electromagnetic field to the micro wireless power receiving coil, which receives and then transforms the electromagnetic field to electrical current to supply power to the micro ultrasonic vibrator.
