Abstract: 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.

Abstract: There is provided markers, systems, and methods for creating and utilizing a marker containing identification information. The embodiments include an identifying marker comprised of high temperature material for tracking a component in a high temperature environment. The marker may be disposed on the component such that the marker is subject to high temperatures while affixed to the component. The marker may provide the ability to track a history of the component the marker is attached to for maintenance.
