The common commitment to limit the use of toxic and environmentally harmful substances and to reduce energy consumption, combined with the ever-increasing demand and need for portable analytical instrumentation, has led research towards the development of miniaturized analytical devices characterized by a reduced consumption of solvents / reagents and usable ""in field"" in compliance with the fundamental principles of GAC (""Green Analytical Chemistry).
In this context, the research activity is focused on the development of low-cost and easy-to-use miniaturized electrochemical and optical analytical devices, using simple constructive approaches based on the use of commonly used instruments (cutting plotter, office or 3D printers, open-source microcontrollers and smartphone) and using eco-friendly and readily available materials (graphite-pencil, paper and cotton). These devices have been used for the determination and quantification of analytes of agro-food and environmental interest
