The silver nanowire membranes are made of silver nanowires with different diameters and different
lengths. They have a disk shape with a diameter of 25mm and a thickness 20 micron. Other sizes
and thicknesses can be custom-synthesized, too.
These silver nanowire membranes can be used in a variety of filtration application due to their high
chemical and high temperature stability. They also allow the trapping of nanoparticles and
biomaterials including viruses. The high electrical conductivity of these membranes may also allow
the direct SEM observation of biospecies without metal coating, which not only simplifies the SEM
observation process, but also eliminates the artifacts caused by metal coating during the SEM
