Detecting Toxins: The Future of Farming!  #sciencefather #researchawards #scientist #pesticide 

The Cobalt-Modified Exfoliated Zirconium Phosphate/Histidine-Functionalized Graphene Quantum Dots-Based Electrochemical Biosensor is an advanced sensing platform designed to enable the ultra-sensitive detection of methyl parathion (MP)—a hazardous organophosphorus pesticide—in agricultural food products 🥦🍎 and environmental water samples 💧🌾. This innovative biosensor integrates cobalt-modified exfoliated zirconium phosphate (Co-ZrP) with histidine-functionalized graphene quantum dots (His-GQDs) to achieve exceptional electrocatalytic activity ⚡, selectivity 🧪, and signal amplification 📈. The unique synergy between these nanomaterials facilitates rapid electron transfer and enhances the biosensor’s responsiveness to MP even at trace levels 🔬, ensuring accurate monitoring and safer consumption of agricultural goods and cleaner aquatic environments. Its practical application showcases potential for real-time, on-site environmental monitoring 🌍 and food safety assurance 🛡️, representing a significant step forward in sustainable agrochemical management and public health protection.

"Optimizing Metal Ion Sensing Using ML" #sciencefather #machinelearning #researcher

This study introduces a machine learning (ML) framework for optimizing photodetector performance in metal ion sensing applications. The proposed system leverages a heterostructure of nitrogen-doped graphene quantum dots (N-GQDs) and gold nanoparticles (Au@N-GQDs). Over 20 supervised ML models were trained and evaluated to identify the most effective algorithm for detecting metal ions.
