Immunoassay technology: Research progress in microcystin-LR detection in water samples

Area of Science:

• Environmental Science
• Analytical Chemistry
• Toxicology

Background:

• Global warming and eutrophication drive frequent cyanobacteria blooms in freshwater ecosystems.
• Cyanobacteria blooms produce potent toxins, such as Microcystin-LR (MC-LR), which threaten aquatic and terrestrial life, including human and animal health.
• Accurate and rapid detection of MC-LR is critical for risk assessment and management.

Purpose of the Study:

• To review and analyze immunoassay detection methods for Microcystin-LR (MC-LR) over the past two decades.
• To compare the advantages and disadvantages of various immunoassay techniques for MC-LR analysis in water samples.
• To discuss current challenges and future trends in MC-LR immunoassay detection.

Main Methods:

• Review of classical enzyme-linked immunosorbent assay (ELISA) for MC-LR detection.
• Analysis of modern immunoassays utilizing optical and electrical signals for MC-LR quantification.
• Evaluation of immunoassay principles and applications in water environmental monitoring.

Main Results:

• Immunoassay technologies offer specific recognition for MC-LR detection.
• Different immunoassay methods (ELISA, optical, electrical) show varying performance characteristics.
• Water samples are the primary matrix for evaluating these MC-LR detection techniques.

Conclusions:

• Immunoassays are vital tools for sensitive and accurate MC-LR detection in environmental monitoring.
• Addressing current challenges in immunoassay performance is key to enhancing MC-LR detection capabilities.
• Future trends focus on improving sensitivity, speed, and portability of MC-LR immunoassays.
