microviscosity

plural microviscosities

1. countableuncountableThe friction experienced by a single particle undergoing diffusion because of its interaction with its environment at the micrometer length scale.

   Both the crowding density and relative size of each co-solute in a mixture will contribute to the measured microviscosity as assessed by altered translational mobility.

   The friction experienced by a single particle can be thought of as a microscopic viscosity (microviscosity) and should not necessarily agree with the bulk viscosity since it is a measure of the probe's local friction whereas bulk viscosity analogously would be the measure of an infinitely large probe.
