Abstract

We show how a single gold nanorod can serve as a multifunctional probe in an organized DNA matrix. Polarization analysis of two-photon luminescence excited with a femtosecond laser enables imaging of the orientation of a single nanorod, which reports the orientation of DNA strands. Carefully controlled photoinduced heating by the same laser is able to degrade the DNA matrix in a highly localized volume.
