Electrochemical Monitoring in Anticoagulation Therapy.

Area of Science:

• Biochemistry
• Analytical Chemistry
• Biomedical Engineering

Background:

• Blood coagulation is a vital physiological process essential for hemostasis.
• Dysregulation of blood clotting can lead to serious health issues, including thrombosis and hemorrhage.
• Anticoagulant medications are critical for managing and preventing thrombotic events but require careful monitoring.

Purpose of the Study:

• To review the stages of blood coagulation.
• To explore common anticoagulants and their enzymatic targets.
• To emphasize electrochemical methods for monitoring anticoagulant therapy.

Main Methods:

• Review of literature on blood coagulation and anticoagulants.
• Categorization of electrochemical sensors into two main types: thrombin activity assays and modified electrode-based methods.
• Analysis of electrode compositions, detection limits, and quantification limits.

Main Results:

• Electrochemical sensors offer precise monitoring of anticoagulant activity.
• Two primary sensor types exist: those measuring thrombin activity and those using modified electrodes.
• Various electrode materials and their performance metrics are detailed, with potential for universal calibration plots.

Conclusions:

• Electrochemical sensing provides a promising avenue for effective anticoagulant monitoring.
• Further development in sensor technology can optimize anticoagulant dosage and patient care.
• The insights presented can advance the field of electrochemical biosensors for therapeutic drug monitoring.
