Description
Laser-Induced Graphene (LIG) offers a cost-effective, scalable platform for electrochemical sensors, driving advancements in environmental monitoring, agriculture, and health diagnostics. Our studies focus on recent developments in LIG-based ion-selective electrodes for nutrient sensing in soil, supporting precision agriculture, and for non-invasive monitoring of metabolites and electrolytes in sweat, enhancing sports performance and health tracking. Additionally, we explore the functionalization of LIG with platinum nanoparticles and the surface tunability of electrodes to improve sensitivity for saliva analysis and nitrite detection in food safety. We also introduce Laser-Induced Graphene Microfluidic Integrated Sensors (LIGMIS), which combine microfluidics with LIG electrodes for real-time ion detection with high selectivity and low detection limits. These sensors enable multiplexed electrochemical detection of pesticides and ions in environmental water monitoring. Incorporating hydrophobic surface tuning and polyethyleneimine coatings, LIGMIS sensors demonstrate enhanced performance and long-term stability across a range of applications, from agriculture to wearable biosensing. This scalable, low-cost approach provides a promising solution for decentralized monitoring in precision agriculture, environmental, and health diagnostics. Looking ahead, we aim to further enhance the selectivity and electrochemical performance of the sensors through the integration of artificial intelligence (AI), which can potentially optimize sensor design by improving stability, sensitivity, and selectivity through data-driven insights.
