Sustainable Sensor Detects Pesticides on Crops
February 7, 2024| |
Scientists in Brazil have produced a plant-wearable sensor that detects the presence of pesticides on fruits and vegetables. This innovation may help address food safety and sustainability issues in agriculture.
Pesticides are typically used on crops to eliminate pests and increase crop yields. However, only 50% of pesticides reach their target. The remaining amount may contaminate the soil, water, and food products.
To help with this issue, researchers from the University of São Paulo and the Federal University of Viscosa created a biodegradable sensor for pesticide detection. The device is made of cellulose acetate derived from wood pulp. Unlike other sensors, the new invention can be placed on the surface of a fruit or vegetable to analyze its pesticide content. Besides being sustainable and plant-wearable, the sensor is also affordable, highly selective, convenient, and easy to use.
