Electrochemical immunosensor

Electrochemical immunosensor functionalized with nanobodies for the detection of the toxic microalgae Alexandrium minutum using glassy carbon electrode modified with gold nanoparticles

Importance:

A biosensors based on electrochemical impedance with unmet sensitivity for toxic microalgae was developed by UNG researchers in collaboration with colleagues at the University of Graz.

• A label free immunosensor for electrochemical detection of the toxic microalgae Alexandrium minutum was constructed
• Its sensitivity is superior to any other diagnostic device proposed so far for such organism
• The biosensor showed high selectivity when tested with control microalgae
• The system is suitable for directly measuring sea water samples
• Inexpensive tool for in situ monitoring of algal blooms in the sea and of ballast water contamination
