microviscosity

Noun

 * 1) The friction experienced by a single particle undergoing diffusion because of its interaction with its environment at the micrometer length scale.
 * 2) * 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.
