In this paper the concept of fashioning a microdetector for laser induced fluorescence based on laser diode excitation is discussed. A plan is discussed to demonstrate this concept by replacing the bench-top detectors of published microelectrochromatographic experiments with a detector based upon a miniature diode laser. The concept of providing autonomous power for the diode laser with microbatteries is discussed and shown to be feasible. Autonomous power for a remote sensor based on microelectrophoresis, a diode laser detector and microbatteries is discussed.
