Abstract: We demonstrate the use of optical patterns, produced by resonant Rayleigh scattering from gold nanorods, as markers by which local deformations can be measured using image correlation techniques. While the use of optical data, in this case from dark-field microscopy, to generate deformational field information (displacements and strains) is not new, the use of the light scattered from gold nanorods as the correlated pattern is new, and has the potential to enable smaller scale measurements even over large deformations. We find excellent agreement between the measured and theoretical deformation and strain fields for two sample polymers with gold nanorod markers. The gold nanorod surface can be modified to make biocompatible nanomaterials, which will be useful for examining mechanical effects in biological tissue.
