Single-cell mass-density measurements using microchannel gradient centrifugation Open
We present a microchannel-based adaptation of mass density-gradient centrifugation for the mass density measurement of cells or microparticles. The workflow consists of three basic steps: Microchannel filling, centrifugation, and microscop…

On the uncertainty of defocus methods for 3D particle tracking velocimetry Open
Defocus methods have become more and more popular for the estimation of the 3D position of particles in flows (Cierpka and Kahler, 2011; Rossi and K ¨ ahler, 2014). Typically the depth positions of particles are ¨ determined by the defocus…

Defocus particle tracking: a comparison of methods based on model functions, cross-correlation, and neural networks Open
Defocus particle tracking (DPT) has gained increasing importance for its use to determine particle trajectories in all three dimensions with a single-camera system, as typical for a standard microscope, the workhorse of today’s ongoing bio…
