Sensor technology based on immunological ELISA analyses combined with various electrochemical detection systems is being developed to quantify phycotoxins in algae and seafood. The use of disposable screen-printed electrodes for the immunosensor development is illustrated. Laboratory responses on contaminated mussels were obtained by domoic acid and saxitoxin sensors with detection limit of 5 and 0.1 ng/ml respectively. Application to algal extracts was also performed to detect domoic acid concentration in phytoplankton populations along Latium (Middle Tyrrhenian Sea, Mediterranean Sea) coast.
