We experimentally demonstrate stable trapping and controlled manipulation of silica
microspheres in a structured optical beam consisting of a dark focus surrounded by light in …

We demonstrate dynamic trapping and manipulation of nanoparticles with plasmonic
holograms. By tailoring the illumination pattern of an incident light beam with a computer …

We review recent advances achieved in the field of surface plasmon-based optical
manipulations. We first discuss enhanced optical forces at the surface of a flat metal film and …

The ability to manipulate small particles of matter using the forces of light, optical trapping,
forms the basis of a number of exciting research areas, spanning fundamental physics …

Optical trapping and patterning cells or microscopic particles is fascinating. We developed a
light sheet-based optical tweezer to trap dielectric particles and live HeLa cells. The …

Since their advent in the 1980s, optical tweezers have attracted more and more attention
due to their unique non-contact and non-invasion characteristics and their wide applications …

In this study, nanoparticles (NPs) of various types and sizes are arranged to enhance both
the omnidirectional light harvesting of solar cells and the light extraction of light emitting …

In this paper we report multiple optical trapping of microscopic dielectric particles using
diffractive optical elements implemented on twisted nematic liquid crystal spatial light …

The ability to manipulate nanoparticles is significant in nanoscale science and technology.
As sizes of the objects scale down to the sub-10 nm regime, it imposes a great challenge for …

Thin-film photovoltaic technologies have an enormous potential to reduce the cost of solar
electricity. However, because thin photoactive layers are used, optical absorption is …
