microrheology

Since the force involved is very weak (order of 10 N), microrheology is guaranteed to be in the so-called linear region of the strain/stress relationship.

The concept of microviscosity is intimately related to the concept of single particle diffusion and can be measured using microrheology.

A related method of passive microrheology involves the tracking positions of a particle at a high frequency, often with a quadrant photodiode.

There are two types of microrheology: passive microrheology and active microrheology.

The rheological properties of the upper mantle for geotherms representative of shield and Cordilleran regions are studied on the basis of olivine microrheology.

Force Spectrum Microscopy (FSM) is an application of active microrheology developed to measure aggregate random forces in the cytoplasm.

Passive microrheology uses the thermal energy (kT) to move the tracers, although recent evidence suggest that active random forces inside cells may instead move the tracers in a diffusive-like manner.

If carefully calibrated, DWS allows the quantitative measurement of microscopic motion in a soft material, from which the rheological properties of the complex medium can be extracted via the so-called microrheology approach.

Passive microrheology uses inherent thermal energy to move the tracers, whereas active microrheology uses externally applied forces, such as from a magnetic field or an optical tweezer, to do so.

I will tell you what happens in soap froths as bubbles move past each other, I will summarize this microrheology, and I will connect it with what people measure in "bulk" measurements on soap froths.

He is most well known for his work on various aspects of the jamming (physics) phenomenon, specifically in colloidal glasses and colloidal supercooled liquids, although his research interests extend broadly into other types of complex fluids, as well as microrheology and granular materials.
