microviscosity

English

Etymology

From micro- +‎ viscosity.

Noun

microviscosity (countable and uncountable, plural microviscosities)

1. The friction experienced by a single particle undergoing diffusion because of its interaction with its environment at the micrometer length scale.
   • 2008, Goins, A.B., H. Sanabria, M. N. Waxham, "Macromolecular crowding and size effects on probe microviscosity", Biophysics Journal 95:5362-5373

     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.

   • 2008, Aron Benjamin Goins, Crowding and size effects on probe microviscosity for polymer cytosolic mimicry‎^[1]:

     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.
