Optofluidic Trapping and Transport Using Planar Photonic Devices   103


          5-6  Summary and Conclusions
               In this chapter we have introduced the concept of “optofluidic trans-
               port” as a means for achieving long-interaction length optical trans-
               port of particles in a microfluidic format using planar dielectric wave-
               guides. We have discussed the advantages of this approach in the
               context of other optical manipulation techniques and commonly used
               microfluidic transport methods such as pressure drive flow and elec-
               trokinetics. An experimental and theoretical overview of the technol-
               ogy has been developed with sufficient detail that most readers
               should be able to replicate the experiments (developing their own
               implementations) and perform equivalently detailed simulations.
               Although numerous technological advantages of optofluidic trans-
               port have been alluded to, we focused here on comparing the advan-
               tages of “optofluidic chromatography” with the state of the art.
