One-step fabrication of the novel electrochemical sensing platform for the ultrasensitive determination of Microcystin-LR

To ensure the safety of the natural ecosystem, it is critical to develop portable, easy-to-operate and environmentally friendly quantitative analytical electrodes for the determination of microcystin-LR (MC-LR) in environmental water. Herein, a simple, mask-free, and one-step method based on laser-induced graphene (LIG) technology is designed for the fabrication of (3D) graphene electrodes integrated with gold nanoparticles (AuNPs). The …
