The present invention relates to a method for removing biopolymer aggregates and viruses from a fluid. In a first step, the biopolymer aggregates are selectively removed by filtration through a porous, polyamide-comprising shaped body having a native surface. In a second step, the biopolymer aggregate-free fluid is filtered through at least one suitable virus-retentive membrane.

Improved resolution and detection of nanoparticles are achieved when a nanopore connecting liquid compartments in a device running on the Coulter principle is provided with fluid lipid walls. The fluid lipid walls are made of a lipid bilayer, and preferably include lipid anchored mobile ligands as part of the lipid bilayer. By varying the nature and concentration of the mobile ligand in the lipid bilayer, multifunctional coatings of lipids are provided.
