Rotational and translational diffusion of colloidal ellipsoids in bulk and at surfaces

Fluorescence Recovery after Photobleaching in Colloidal Science: Introduction and Application

“…While FRAP is a very flexible approach, single-particle tracking (SPT), , fluorescence correlation spectroscopy (FCS), image correlation spectroscopy (ICS), raster image correlation spectroscopy (RICS), and nuclear magnetic resonance (NMR) diffusometry are also other methods for determining molecular motion. FRAP has shown to be a very valuable complement to FCS and SPT, which both need extremely dilute samples (usually in the nanomolar range).…”

A forward reconstruction, holographic method to overcome the lens effect during 3D detection of semi-transparent, non-spherical particles

“…The ability to resolve the three-dimensional (3-D) position and orientation of a dynamic, orientable particle is crucial to analyze systems seen in various fields such as biology, rheology, oceanography and industrial safety. [3][4][5][6][7][8][9] Specifically in microbiology, the collective motion of microswimmers such as bacteria cells near phase boundaries governs the formation of biofilms, which is crucial in the field of microbial pathology and ecology. [10][11][12][13] In microrheology, the 3-D translational and rotational motion of a non-spherical particle can be used to probe the rheological properties of the suspending fluid.…”

Dynamics of prolate spheroids in the vicinity of an air–water interface

“…8 Differently from spherical particles, the dynamics of colloids with complex morphology is still almost unexplored. [10][11][12][13][14] Earlier studies have mostly focused on spheroidal particles close to solid boundaries, [15][16][17] as this morphology is the simplest after the spherical one. Because of anisotropy, particle hydrodynamic interactions with the confining interface result in a complex tensorial mobility, which demands the knowledge not only of the position but also of the orientation and the aspect ratio (i.e., the ratio between the axes lengths) of the spheroid.…”
