Nanoradiators allow precise optical manipulation of nanoparticles (w/video)

Wed, 10/03/2018 - 11:05
Researchers have developed a new type of optical manipulation method to achieve versatile manipulation of objects with different sizes and types using optical heating. In this new technique, nanoparticles get trapped at temperature hot spots instead of electrical hot spots, which demonstrates a different working mechanism and approach from the traditional optical manipulation techniques. Due to this unique working principle, stable trapping of large metallic nanoparticles and miniscule quantum dots on single nanoantennas with extremely low optical power is achieved.
