Sensor detects pesticides using material thinner than a strand of hair

Researchers at the Vietnam Academy of Science and Technology have developed a sensor electrode using a composite material of graphene, carbon nanotubes (CNTs), and gold nanoparticles that can detect pesticide residues at concentrations as low as parts per billion (ppb). This advancement is significant for the field of advanced carbon materials as it enhances the sensitivity and functionality of sensors, contributing to improved agricultural product monitoring and food safety.
