Development of low cost device for in-situ algae monitoring

Water quality monitoring for Harmful Algal Blooms (HABs) in large coastal and inland environments currently relies on techniques that are expensive and, in the case of aerial photography, are unable to provide data necessary to help predict future events. The development of a technique that is inexpensive and simple enough for anyone to use is important to the research surrounding HABs and the dangerous conditions they can bring about for aquatic and human life. The goal of this research is the development of a prototype, handheld, low cost device for in-situ monitoring of potentially harmful algae species whose presence could lead to a HAB. Using visible light spectrophotometry incorporated with a near-field enhanced nano biosensor, the concentrations of harmful algae in water samples can be measured and determined to be safe or dangerous, prompting further data collection and surveillance.
