IR-biosensor for in situ detection of toxic algae alexandrium minutum

Toxic algal blooms are a public health issue and constitute a menace for coastal areas. The potentiality of a chalcogenide optical fibre biosensor, operating in the mid-infrared (MIR) spectral domain, is studied. In order to monitor blooms of toxic algae, more specifically Alexandrium minutum specie, two ways are explored: immuno-biosensing and DNA identification.
