This paper describes the combination of near-field optical forces (such as those used in optical traps) to confine nanoscopic matter inside a liquid core-slot waveguide and photon scattering forces to transport them. The waveguide overcomes the diffraction limits of conventional optical trapping systems to manipulate objects down to tens of nanometres in scale. As the waveguide is linear, it can also manipulate extended biomolecules demonstrated by trapping and transporting DNA molecules.
