Microplastics detection by impact electrochemistry
AI summary Read the abstract
This paper explores impact electrochemistry—a technique where individual particles colliding with an electrode generate detectable electrical pulses—as a method for detecting and characterizing microplastics in water. The approach offers the potential for rapid, single-particle detection without the need for complex sample preparation or optical instruments, which could make microplastic monitoring cheaper and more accessible. Developing faster and simpler detection methods is important for scaling up environmental monitoring programs.

Protocol for low-cost quantification of microplastics through electrochemical impedance spectroscopy from aqueous matrices
AI summary Read the abstract
Most methods for detecting microplastics in water require expensive equipment or time-consuming laboratory steps. This study presents a simple protocol using electrochemical impedance spectroscopy (EIS) — measuring how microplastics change the electrical resistance of a solution — to rapidly and cheaply quantify plastic particles in water samples. Validated against conventional optical methods, the approach could make routine microplastic monitoring more affordable and accessible, particularly for lower-resource settings or high-throughput screening applications.
