<p>A system for material excitation in microfluidic devices is described. Aspects of the invention resemble a submerged periscope when in use. A reflecting surface (20) may be provided in connection with a simple support (18). The reflecting surface (20) is used to direct a laser beam (22) along one or more microfluidic trenches or channels (6). Alternately, a reflecting surface (20) may be provided on a prism. Directing a beam (22) along multiple paths is preferably accomplished by scanning a single laser across or around the reflecting surface (20) provided. Provision may be made for at least a portion of the support (18) to be used as an electrode to assist in electrokinetically driving fluids and/or ions within the microfluidic device.</p> |
