The influences of non-Fermi liquid correlations and spin-orbit scattering on the transport properties of quantum nanostructures connected to interacting leads are studied. Signatures of the spin are investigated in the transport. One-dimensional quantum dot is studied in the sequential tunnelling regime using the master equation approach. Quantum coherent conductance is calculated using the transfer matrix method for a quasi-one dimensional system with the Rashba coupling Hamiltonian, and for a two -dimensional quantum dot in a multi-terminal geometry modelled by the Ando Hamiltonian. In the sequential tunnelling regime, states with a higher total spin can be stabilized by suitably adjusting bias and gate voltages. Spin polarized current can be achieved by locally applying a magnetic field. For coherent linear transport through a multi-terminal device at zero magnetic field, we find a spin polarized current at certain energies, induced by spin-orbit scattering.
