Sub-piconewton force detection using micron-size wire deflections

Abstract

The mechanical properties of nanostructured wires obtained by co-assembly of iron oxide particles are studied. The intrinsic magnetic properties of the wires are used to induce and quantify the bending of the one-dimensional objects. From the relationship between the deflection and the magnitude of the magnetic field, the elastic rigidity and Young modulus of the wires are determined. Young moduli in the megapascal range are obtained and are consistent with sub-piconewton force detection.
