Pesticide residues on common produce like apples, spinach, or tomatoes pose toxicological risks. Reliable, accessible detection methods are crucial to ensure safer daily consumption.


SPE sensors use enzyme-functionalized printed electrodes. When pesticides interact, electrochemical signals are generated and instantly read via handheld analyzers or smartphone-connected portable detection systems.


Ideal for farms, markets, or homes, SPE sensors allow quick, accurate pesticide testing on strawberries, grapes, or greens—empowering safer food decisions anytime, anywhere.


Alphaion develops eco-friendly SPE sensors enhanced with nanomaterials. Their scalable platforms support real-time, on-site pesticide monitoring in agricultural fields, retail points, and household kitchens.


SPE technology and Alphaion’s innovation make food safety simple. Test your fruits and vegetables quickly, reliably, and affordably—ensuring clean, healthy, pesticide-free produce.
