Dujovne, I. (author), Kerssemakers, J. (author), Capello, G. (author), Dekker, C. (author)We present a novel high-resolution technique for single-molecule experiments, viz., differential traveling wave tracking. This is an interference-based scattering technique where we use gold nanoparticles for high scattering intensities and incorporate differential measurements along one in-plane direction to subtract mechanical noise and drift...journal article 2010
