Capturing Nano- and Micro-Objects in Predesignated Sites using Suspended Membranes

This invention introduces a novel method for capturing and positioning nano- and micro-scale objects at predetermined locations using suspended membranes. The technology leverages precisely engineered membrane structures to facilitate the controlled trapping of particles without requiring complex optical or mechanical manipulation techniques. This technique allows for deterministic, rather than random, placement of nanoparticles, which allows for precise spatial control of nanoscale objects. This approach enhances precision in microfabrication, biosensing, and nanotechnology applications.

Background: 
In many scientific and industrial applications, accurately positioning nano- and micro-scale objects is critical. Existing methods often rely on optical tweezers, electrostatic forces, or fluidic techniques, which can be inefficient, costly, or limited in scalability. This invention provides a more effective and scalable solution by utilizing suspended membranes to achieve precise and passive object capture. By combining top-down lithographic patterning to define capture sites with bottom-up particle capture using centrifugal force, it enables new possibilities in advanced manufacturing, biotechnology, and sensing technologies.
