A programmable optical angle clamp for rotary molecular motors

open access: yes, 2007
Optical tweezers are widely used for experimental investigation of linear molecular motors. The rates and force dependence of steps in the mechanochemical cycle of linear motors have been probed giving detailed insight into motor mechanisms. With similar

An Adjustment Strategy for Tilted Moiré Fringes via Deep Q-Network

open access: yesPhotonics
Overlay accuracy, one of the three fundamental indicators of lithography, is directly influenced by alignment precision. During the alignment process based on the Moiré fringe method, a slight angular misalignment between the mask and wafer will cause ...

Novel schemes for the optical manipulation of atoms and molecules [PDF]

open access: yes, 2009
The range of atoms which can be cooled by lasers is limited to those which have a closed two level structure. Several schemes have been proposed which aim to extend this range by using coherent control of the particle momenta, but none have yet been ...

Lensless optical manipulation with an evanescent field

open access: yesOptics Express, 2008
We report on the numerical study to model a lensless optical manipulation trap to investigate some observed features as guiding and modulation effects caused by a micro-sphere. For this we calculate the field distribution and force exerted upon a micrometer-sized spherical dielectric particle in an evanescent field.

Applications of microfluidics and optical manipulation for photoporation and imaging

open access: yes, 2015
Optical manipulation covers a wide range of techniques to guide and trap cells using only the forces exerted by light. Another optical tool is photoporation, the technique of injecting membrane-impermeable molecules using light, which has become an ...
