The disclosure relates to a method for determining a hydrodynamic size of an object, such as a nano-sized object, said method comprising the steps of: &#x2014;providing a fluid interface, &#x2014;linking said object to said fluid interface thereby providing a linked object, whereby the movement of said linked object is restricted by virtue of being linked to said fluid interface, &#x2014;providing and determining a hydrodynamic shear force that acts on said linked object, &#x2014;tracking the movement of said linked object, and &#x2014;calculating the hydrodynamic size of the object using the Einstein-Smoluchowski relation.
