Development of 3D Printed Microfluidics Lab-on-Chip Colorimetric System in Rapid Testing of Nutrient for Precision Agriculture: Simulation and Validation

The advancement of microfluidic systems enables rapid development of Lab-On-Chip (LOC) for the applications in different fields, such as biomedical diagnostics, environmental monitoring, healthcare and agriculture. Microfluidics LOC is integrated device platform for manipulations of fluids within microscale to perform one or more laboratory functions. Smart technologies have now penetrated every aspect of modern life and is ubiquitous. 3D printed sensors, Internet Of Things (IOT) and smartphone have been used as point of care device. A similar approach can be extended in precision agriculture for nutrient detection. The integration of Microfluidics Lab- On -Chip (LOC), smart sensing and IOT presents a transformative approach to nutrient management in precision agriculture. 3D printed Microfluidics LOC technologies enable the precise analysis of nutrients and allowing for real-time monitoring and optimization of plant growth conditions. Integrating electronic sensors within the microfluidic systems, farmers can receive continuous data on nutrient levels for enhancing decision-making processes. This collaborative approach not only streamlines rapid nutrient detection but also promotes sustainable agriculture. The proposed system has simulation comparison of Y channel and Y serpentine channel with chamber mixer in COMSOL with 3D printed chip design validation. We integrate design simulation and experimental validation.
