DESCRIPTION:Optical forces and trapping may dictate the organization and m
 anipulation of colloidal and biological matter at the nanoscopic through t
 o macroscopic level. Advanced photonics using novel holographic beam shapi
 ng to alter the phase and/or amplitude of light has become an important fe
 ature in this topic area. By creating more elaborate 2D and 3D light patte
 rns (beam shaping) one can create an optical landscape. Particle and cellu
 lar motion on such a landscape will enhancing our ability to move and sort
  particles and importantly\, create 2D and 3D arrays of micro and nanopart
 icles [1\, 2].  The use of “shaped" light fields such as Bessel and Airy
  modes have continued to play a key role in the field as well as the abili
 ty to propagate light through turbid media (disordered materials) [3]. Fin
 ally exploiting optical angular momentum can assist in realising new metho
 ds of performing microrheology of gases [4]\n\n[1]  K. Dholakia and T. Ciz
