Since their invention just over 20 years ago, optical traps have emerged as a powerful tool
with broad-reaching applications in biology and physics. Capabilities have evolved from …

In the first part of the seventeenth century, the German astronomer Johannes Kepler
proposed that the reason comet tails point away from the sun is because they are pushed in …

Optical tweezers (infrared laser-based optical traps) have emerged as a powerful tool in
molecular and cell biology. However, their usefulness has been limited, particularly in vivo …

Optical tweezers are used to apply calibrated forces to human erythrocytes, via small silica
beads bound to their membrane. The shear modulus μ of the membrane is inferred from …

The confinement of liposomes and Chinese hamster ovary (CHO) cells by infrared (IR)
optical tweezers is shown to result in sample heating and temperature increases by several …

For several decades optical tweezers have proven to be an invaluable tool in the study and
analysis of myriad biological responses and applications. However, as with every tool, they …

Molecular excitation by two-photon absorption holds great promise for vital imaging of
biological systems using laser-scanning microscopy. Fluorescence microscopy, which can …

A study on clonal growth in Chinese hamster ovary (CHO) cells was conducted after
exposure to optical trapping wavelengths using Nd: YAG (1064 nm) and tunable titanium …

Abstract This Resource Letter provides a guide to the literature on optical tweezers, also
known as laser-based, gradient-force optical traps. Journal articles and books are cited for …

The equilibrium position of a low-index particle in an optical-vortex trap was experimentally
measured for two different systems: a buoyant hollow glass sphere in water and a density …
