Abstract
A method for evaluating the integrity of microfiltration, ultrafiltration and nanofiltration membranes, which method comprises passing a liquid that contains a substantially mono-dispersed population of nano-probes through said membrane to form a permeate and testing said permeate for the presence of said nano-probes, wherein the non-detection of said nano-probes in said permeate indicates that said membrane is substantially intact.
