metalsensing
Metalsensing is the detection and quantification of metallic species, including metal ions and elemental metals, using sensor-based approaches. It encompasses chemical, electrochemical, optical, and spectroscopic techniques and is used to study environmental samples, industrial processes, and biological systems.
Common sensing platforms include electrochemical sensors such as ion-selective electrodes and voltammetric or impedance-based devices, often
Applications span monitoring heavy metals in water and soil, quality control in food and beverages, detection
Key performance metrics include limit of detection, dynamic range, selectivity against interfering ions, response time, stability,
Ongoing developments aim at higher sensitivity, multiplexed sensing of multiple metals, integration with smartphones and wireless
