The advent of microfluidics has allowed for the miniaturization of analytical devices. The incorporation of microfluidics allows for consumption of less reagents, lower costs and reactions cable of being performed on a smaller scale. Nutrients, such as phosphate, are central in many environmental processes within the marine environment, including several microbial, plant and animal metabolic processes. The microfluidic sensor is a component within an autonomous sensing platform developed for an FP7 project.
The detection method is based on a combination of microfluidic analytical systems, colorimetric reagent chemistry, low-cost LED-based optical detection and wireless communication. Using fabrication techniques, CNC micro-milling, laser ablation and thermal bonding, to manufacture and assemble the microfluidic sensor.The sensor been tested through a number of deployments in areas of environmental interest, such as Ny-Aselund Svalbard on the Italian Artic Base, Sardinia Italy, CNR Italy testing Lagoon and the Mediterranean onboard the RV Minvera Uno.
