TLDR
In this paper, a micro-fabricated Fresnel zone plate was used to trap 2μm diameter beads in water with stiffness comparable to conventional optical tweezers.Abstract:
We demonstrate the trapping of beads in water with a microfabricated Fresnel zone plate. Beads are loaded onto the microfabricated optical traps using conventional optical tweezers and fluorescence microscopy is used to track bead position. Analysis of the bead position as a function of time is used to determine trapping stiffness. We present experiments showing the three-dimensional trapping of 2μm diameter beads with trapping stiffnesses that are comparable to conventional optical tweezers when the zone plate efficiency is taken into account.read more

Nanomanipulation Using Silicon Photonic Crystal Resonators
TL;DR: The trapping of 48 nm and 62 nm dielectric nanoparticles is demonstrated along with the ability to transport, trap, and manipulate larger nanoparticles by simultaneously exploiting the propagating nature of the light in a coupling waveguide and its stationary nature within the resonator.

Bead movement by single kinesin molecules studied with optical tweezers
TL;DR: The results of this study are consistent with a model in which kinesin detaches briefly from the microtubule during a part of each mechanochemical cycle, rather than a models in whichKinesin remains bound at all times.
