Detection of microbeads in self-developed in vitro bioimpedance assay: A proof of principle study
AI summary Read the abstract
Researchers developed a bioimpedance spectrum (BIS) measurement technique to detect microbeads in cell cultures in vitro, demonstrating as a proof-of-principle that the electrical properties of plastic particles can be exploited for detection in biological systems.
Research on microand nanoplastics is attracting greater interest. As current studies have shown, their presence is in environmental elements and living organisms, thus investigating their toxicity is of crucial concern. In previous work, the authors have developed a unique bioimpedance spectrum (BIS) measurement technology to study the biological processes of cell cultures in vitro. Exploiting the electrical properties of the material composition of plastics, it seems trivial to investigate how the BIS technique can detect them. Therefore, BIS data of plastic beads of 6 mm diameter were recorded at different concentrations. The correlation between microbead concentration and BIS data is established. The proof-of-principle measurements are successful and the technology is ready for testing with live cells.

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.
