Plant pests exert serious effects on food production for which global crop yields are annually reduced by ~20-40%. Hence to meet world’s food needs, loses of food due to crop pests must be reduced. Herein the protocol describes a unique covalent functionalization of the silicon dioxide based MEMS devices for robust and efficient optical sensing of female sex pheromones of the pests like Helicoverpa armigera. The chemically functionalized devices are also capable of measuring the concentration of pheromone at the femtogram level which is much below the pheromone concentration at the time of infestation in an agricultural field. Again reversible use and absolutely trouble free transportation of these pheromone nanosensors heightens their commercial potentials. Overall, a novel and unique protocol for the selective and reversible sensing of female sex pheromones of certain hazardous pests is reported herein which may be efficiently and economically carried forward from the research laboratory to the agricultural field.
