The MariaBox device includes novel parts that allow it to autonomously operate in the field for up to 6 months. 

Automatic filter exchange mechanism: This module is responsible for automatically replacing all filters within the device before any new measurement

Biosensors storage and transfer mechanism: This module is responsible for storing the biosensors in a controlled environment when they are not used, as well as for transferring a sensor to the analysis chamber, each time a new measurement needs to be taken

Pipes cleaning and sample delivery mechanism: This module is responsible for cleaning all system pipes before and after each measurement

Optical analysis module: This is responsible for reading the biosensor’s output

The integrated prototype: The aforementioned modules, together with other components and conventional modules have been combined to deliver the integrated device. The device has been developed as a marine environment analysis device for monitoring chemical and biological pollutants while installed in a buoy or onboard a maritime means of transport
