Methods and systems are provided for concentrating particles (e.g., bacteria, viruses, cells, and nucleic acids) suspended in a liquid. Electric-field-induced forces urge the particles towards a first electrode immersed in the liquid. When the particles are in close proximity to (e.g., in contact with) the first electrode, the electrode is withdrawn from the liquid and capillary forces formed between the withdrawing electrode and the surface of the liquid immobilize the particles on the electrode. Upon withdrawal of the electrode from the liquid, the portion of the electrode previously immersed in the liquid has particles immobilized on its surface.

The present invention relates generally to nanocomposite materials. The present invention relates more particularly to hybrid fibers as well as devices including them and methods for making them. Accordingly, one aspect of the invention is a hybrid fiber including a plurality of nanowires, each nanowire having a length, a width, and a thickness, the length being at least 10 times the width and at least 10 times the thickness; and a plurality of binder elements, each binder element having a length, a width, and a thickness, each substantially smaller than the average length of the nanowires and at least one of which is less than about 10 nm in dimension, the binder elements being arranged to intercouple individual nanowires. In certain embodiments, the binder elements are carbon nanotubes, and the nanowires are formed from silicon carbide.
