Single particle tracking fluorescence microscopy was used to study two late endosomal proteins, Rab7 and LAMP1, that appear to be highly colocalized in static fluorescence microscopy images. Imaging these proteins simultaneously reveals that Rab7 and LAMP1 undergo periods of separation within the cell. Single particle tracking carried out during these periods of separation shows that Rab7-vesic...

Particle pair statistics of inertial particles having average Stokes numbers 2.1 and 14 are measured in isotropic turbulence at a Reynolds number Re? = 240. The radial distribution function (RDF) mean relative approach velocity obtained small separation distances using 2-frame stereoscopic particle tracking velocimetry (stereo-PTV). At distance, the RDF varies by an order magnitude range invest...

This paper presents results of the focussing and separation of particles in microchannels using specially designed and integrated microelectrodes. The behaviour of a range of particle sizes, down to -5Onm, were numerically simulated in microchannels containing the electrodes. The results of the simulations were then compared with the experimental results and discussed with regard to both the un...
