چکیده

A multiple-trap single-beam scanning laser tweezer system was developed and characterized. Different stationary and mobile multiple-trap modes were generated for polystyrene beads in a water environment. Trapping efficiency and stability were investigated for several dynamic parameters such as transition time between the sites, waiting time on a single site, number of trapping sites, and IR laser power. Optimal parameters for efficient generation of complex arrays and matrices were determined. We demonstrate an example of a single laser beam multiple-trap application by measuring the trap's stiffness in water for our laser tweezer setup.

Laser tweezer controlled solid immersion lens for high resolution imaging in microfluidic and biological samples

A novel technique is presented which integrates the capacity of a laser tweezer to optically trap and manipulate objects in three-dimensions with the resolution-enhanced imaging capabilities of a solid immersion lens (SIL). Up to now, solid immersion lens imaging systems have relied upon cantilever-mounted SILs that are difficult to integrate into microfluidic systems and require an extra align...

Nanoplasmonic Tweezers Visualize Protein p53 Suppressing Unzipping of Single DNA-Hairpins

Here we report on the use of double-nanohole (DNH) optical tweezers as a label-free and free-solution single-molecule probe for protein–DNA interactions. Using this approach, we demonstrate the unzipping of individual 10 base pair DNA-hairpins, and quantify how tumour suppressor p53 protein delays the unzipping. From the Arrhenius behaviour, we find the energy barrier to unzipping introduced by...

Practical guide to the realization of a convertible optical trapping system.

In this article, we provide a detailed guide to the construction of a convertible optical trapping system for either single-beam or counter-propagating trap. The single-beam trap maintains all the functionalities that a conventional optical tweezer has. While the counter-propagating trap allows for the trapping of particles that single-beam trap cannot handle. The counter-propagating trap can b...

Theoretical Aspects of Single-beam Multitrapping Acoustical Tweezers

1 Abstract The concept of a multitrapping acoustical tweezer based on a focused ultrasound beam is presented and theoretically investigated. The beam is described in the paraxial approximation and it is generated by a concave transducer. The resulting focused beam exerts a radiation force on a small particle that is much smaller than the incident wavelength (i.e. the so-called Rayleigh scatteri...
