Fluorescent sensing is one of the most broadly used methods to analyze particles or cells of interest. We develop a cost effective integrated portable fluorescent sensing system using light emitting diodes (LEDs) and a silicon photomultiplier. The system provides simple and fast measurements, which can be a viable option for on-site detection and in resource-limited settings. We have demonstrated a handheld and field-deployable system for microalgae co-culture detection in collaboration with Drs. M. T. Gutierrez-Wing and K. A. Rusch. Our goal is to develop an LED-based generic fluorescent sensing platform.
