Optical Trapping “Virometry”

Optics in the Life Sciences, 2013
We present an optical trapping “virometry” that allows sorting of nanoscale particles such as viruses under physiological conditions. As an example, we use this technique to quantitate heterogeneities among individual HIV-1 virions at single-molecule resolution.

Calibration of optically trapped nanotools

Nanotechnology, 2010
Holographically trapped nanotools can be used in a novel form of force microscopy. By measuring the displacement of the tool in the optical traps, the contact force experienced by the probe can be inferred. In the following paper we experimentally demonstrate the calibration of such a device and show that its behaviour is independent of small changes ...

Microinstrument gradient-force optical trap

Applied Optics, 1999
A micromachined fiber-optic trap is presented. The trap consists of four single-mode, 1064-nm optical intersection. The beam fibers mounted in a micromachined silicon and glass housing. Micromachining provides the necessary precision to align the four optical fibers so that the outputs have a common intersection forms a strong three-dimensional ...
