A cartridge electrochemical system refers to a portable and often disposable device designed for performing electrochemical analyses. These systems typically integrate all necessary components for an electrochemical measurement onto a single, small platform, often resembling a credit card or a small USB drive. The primary advantage of a cartridge electrochemical system is its convenience and ease of use, eliminating the need for complex laboratory equipment and extensive sample preparation.

These cartridges usually contain integrated electrodes, microfluidic channels for sample and reagent delivery, and sometimes even a small power source or communication interface. The electrodes are strategically patterned on the cartridge surface, and their design is optimized for specific analytical tasks. Microfluidics allows for precise manipulation of small volumes of liquid, enabling efficient mixing of samples with reagents and controlled transport to the electrode surface.

The operation of a cartridge electrochemical system typically involves introducing a sample and possibly a reagent into a designated port on the cartridge. This is then placed into a reader device, which provides the electrical interface and processing capabilities. The reader applies specific potentials to the electrodes and measures the resulting current or potential changes. These electrochemical signals are then correlated to the concentration of the analyte of interest.

Cartridge electrochemical systems find applications in various fields, including medical diagnostics, environmental monitoring, food safety testing, and point-of-care diagnostics. Their portability and single-use nature make them suitable for field testing and rapid screening. The miniaturization and integration of components contribute to reduced cost, faster analysis times, and improved accessibility to electrochemical analysis.
