Diagnosing human blood clotting deficiency.

Area of Science:

• Biomedical Engineering
• Analytical Chemistry

Background:

• Blood clotting factors are vital for hemostasis; deficiencies can lead to excessive bleeding.
• Accurate diagnosis of clotting factor deficiencies significantly reduces mortality risks.
• Factor IX and thrombin are key clotting factors with clinical relevance in bleeding and thrombosis.

Purpose of the Study:

• To overview biosensor technologies for detecting critical clotting factors.
• To highlight the application of biosensors in diagnosing clotting factor deficiencies.
• To review methods for detecting factor IX and thrombin.

Main Methods:

• Antibody and aptamer probes are utilized for capturing clotting factors on sensor surfaces.
• Various biosensing platforms, including Surface Plasmon Resonance (SPR) and electrochemical aptasensors, are discussed.
• Techniques like evanescent-field-coupled waveguide-mode sensing and metal-enhanced fluorescence are evaluated.

Main Results:

• Biosensors demonstrate potential for high-performance sensing of clotting factors.
• Factor IX and thrombin detection using biosensors is well-documented.
• Improvements in biosensor technology enhance sensitivity and specificity for factor detection.

Conclusions:

• Biosensors provide a viable tool for the medical diagnosis of clotting factor deficiencies.
• Effective detection of factor IX and thrombin can aid in managing bleeding disorders and thrombotic risks.
• Advancements in biosensing platforms pave the way for improved clinical diagnostics.
