ABSTRACT:
A system for material excitation in microfluidic devices is described. Aspects of the invention resemble a submerged periscope when in use. They allow for light to be redirected along a more advantageous trajectory as does the maritime device. A prism with a reflecting surface may be used to direct a laser beam along one or more microfluidic trenches or channels. Alternatively, a reflecting surface may be provided in connection with a simple support. Directing a beam along multiple paths is preferably accomplished by scanning a single laser across or around the reflecting surface provided. Provision may be made for at least a portion of the submersible used to function as an electrode to assist in electrokinetically driving fluids and/or ions within the microfluidic device.
