Description: This thesis presents the development of a system for single cell manipulation using radiation pressure generated forces. Two methods of cell manipulation techniques were investigated: laser tweezing and laser guiding. In laser tweezing, single mode tensed fiber, microfabricated using a molecular fluorine (F2) excimer laser system, were used to trap live biological cell. The lens fibers were designed according to an ASAP2005 optical simulation using beam propagation method (BPM) and a MatLab surface profile modelling. In the second part, an integrated microfluidic device was designed and fabricated for the cell guiding experiment. The device consists of microfluidic channels interconnected with optical waveguides. The radiation pressure carried by the light propagating in the waveguide deflected cells into a transverse microfluidic channel perpendicular to the original direction of flow.
