Nutrients such as Phosphate, Ammonia, Nitrite and Nitrate are central in any environmental processes, including several microbial, plant and animal metabolic processes. The nutrient platform is based on a combination of microfluidic analytical systems, colorimetric reagent chemistries, low cost LED based optical detection and wireless communications. Each component was developed, assessed and optimised to evaluate the suitability before being integrated to form a working pre-competitive prototype
