Impact of complex surfaces on biomicrorheological measurements using optical tweezers

Autor: Shu Zhang, Timo A. Nieminen, Halina Rubinsztein-Dunlop, Alexander B. Stilgoe, Lachlan J. Gibson

Publikováno v: Lab on a Chip. 18:315-322

The characterisation of physical properties in biologically relevant processes and the development of novel microfluidic devices for this purpose are experiencing a great resurgence at present. In many of measurements of this type where a probe in a

Hydrodynamic forces in optical tweezers

Autor: Lachlan J. Gibson

Optical tweezers uses light to control and trap microscopic entities including spherical particles, cells or even three dimensionally (3D) printed structures. In most cases the trapped microscopic object is surrounded by a fluid, such as water, and t

Measuring local properties inside a cell‐mimicking structure using rotating optical tweezers

Autor: Halina Rubinsztein-Dunlop, Lachlan J. Gibson, Shu Zhang, Timo A. Nieminen, Alexander B. Stilgoe

Publikováno v: Journal of Biophotonics. 12

Exploring the rheological properties of intracellular materials is essential for understanding cellular and subcellular processes. Optical traps have been widely used for physical manipulation of micro- and nano-objects within fluids enabling studies

Machine learning wall effects of eccentric spheres for convenient computation

Autor: Alexander B. Stilgoe, Shu Zhang, Lachlan J. Gibson, Halina Rubinsztein-Dunlop, Timo A. Nieminen

Publikováno v: Physical review. E. 99(4-1)

In confined systems, such as the inside of a biological cell, the outer boundary or wall can affect the dynamics of internal particles. In many cases of interest both the internal particle and outer wall are approximately spherical. Therefore, quanti

Theory and practice of simulation of optical tweezers

Autor: Shu Zhang, Isaac C. D. Lenton, Alexander B. Stilgoe, Lachlan J. Gibson, Anatolii V. Kashchuk, Halina Rubinsztein-Dunlop, Ann A. M. Bui, Timo A. Nieminen

Computational modelling has made many useful contributions to the field of optical tweezers. One aspect in which it can be applied is the simulation of the dynamics of particles in optical tweezers. This can be useful for systems with many degrees of

Active rotational and translational microrheology beyond the linear spring regime

Autor: Timo A. Nieminen, Halina Rubinsztein-Dunlop, Lachlan J. Gibson, Alexander B. Stilgoe, Shu Zhang

Active particle tracking microrheometers have the potential to perform accurate broad-band measurements of viscoelasticity within microscopic systems. Generally, their largest possible precision is limited by Brownian motion and low frequency changes
