A Low-cost Fresnel Lens Fluorometer to Detect Fecal Contamination in Drinking Water in Realtime
Conference
We report the detection of tryptophan at sub-ppb levels for a fluorometer based on Fresnel lenses and low-cost electronics. These fluorometers can be used to detect fecal contamination in drinking water, indicated by tryptophan-like fluorescence.
