Semiconductor nanowires have attracted extensive interest as one of the best-defined
classes of nanoscale building blocks for the bottom-up assembly of functional electronic and …

All-photonic integrated circuits are promising platforms for future systems beyond the
limitation of Moore's law. Over the last several decades, one-dimensional (1D) nanowires …

Acoustic tweezers use sound radiation forces to manipulate matter without contact. They
provide unique characteristics compared with the more established optical tweezers, such …

Optical tweezers are devices that use a single, strongly focused laser beam for the remote,
noncontact trapping and manipulation of microscopic objects. Since the first demonstration …

Optical trapping and manipulation of micrometre-sized particles was first reported in 1970.
Since then, it has been successfully implemented in two size ranges: the subnanometre …

Semiconductor nanowires, by definition, typically have cross-sectional dimensions that can
be tuned from 2–200 nm, with lengths spanning from hundreds of nanometres to millimetres …

It has been over 20 years since the pioneering work of Arthur Ashkin, and in the intervening
years, the field of optical tweezers has grown tremendously. Optical tweezers are now being …

Single-molecule biophysics has transformed our understanding of biology, but also of the
physics of life. More exotic than simple soft matter, biomatter lives far from thermal …

Optical trapping is an established field for movement of micron-size objects and cells.
However, trapping of metal nanoparticles, nanowires, nanorods and molecules has received …

One crucial challenge for subwavelength optics has been the development of a tunable
source of coherent laser radiation for use in the physical, information and biological …
