Light Polarization Enables Reversible Nanoparticle Transport Without Phase Gradients
Scientists have developed a novel optical manipulation technique that transports nanoparticles along beam edges using only polarization control. This approach enables reversible direction switching and creates tunable trapping potentials without phase gradients.
Breakthrough in Optical Nanoparticle Manipulation
Researchers have unveiled a groundbreaking method for controlling nanoparticle movement using light polarization, according to a recent study published in Nature Communications. The technique enables tunable and reversible transport of single nanoparticles along flat-top beam edges without requiring in-plane phase gradients, sources indicate. This represents a significant advancement beyond conventional optical tweezers, offering new possibilities for nanoscale manipulation and assembly.
