This review gives a survey on the state of the art of pesticide detection using flow-based biosensing systems for sample screening. Although immunosensor systems have been proposed as powerful… Expand
Highly sensitive amperometric immunosensors for microcystin detection in algae.
The presence of cyanobacterial toxins in water and algae pose a health hazard for animals and humans, due to their tumour-promoting activity and carcinogen effects. The use of simple, rapid and… Expand
Identification of ciguatoxins in a shark involved in a fatal food poisoning in the Indian Ocean
Severe food poisoning events after the consumption of sharks have been reported since the 1940s; however, there has been no clear understanding of their cause. Herein, we report for the first time… Expand
Enzyme sensor for the electrochemical detection of the marine toxin okadaic acid.
An enzyme sensor for the electrochemical detection of the marine toxin okadaic acid (OA) has been developed. The strategy was based on the inhibition of immobilised protein phosphatase (PP2A) by this… Expand
Electrochemical biosensors as a tool for antioxidant capacity assessment
Oxidative stress arises from the excess of free radicals due to environmental or behavioural stressors, or simply to a malfunction of the antioxidant production. It produces damage to lipids,… Expand
Enzyme inhibition-based biosensor for the electrochemical detection of microcystins in natural blooms of cyanobacteria.
An electrochemical biosensor for the detection of microcystin has been developed based on the inhibition of the protein phosphatase 2A (PP2A) by this cyanobacterial toxin. The enzyme has been… Expand

Protein phosphatase inhibition assay (PPIA), Neuroblastoma cell-based assay (Neuro-2a CBA) and LC-MS/MS analysis revealed for the first time the production of okadaic acid (OA) by a Prorocentrum… Expand
Protein phosphatase inhibition assays for okadaic acid detection in shellfish: Matrix effects, applicability and comparison with LC–MS/MS analysis
Abstract The applicability of the protein phosphatase inhibition assay (PPIA) to the determination of okadaic acid (OA) and its acyl derivatives in shellfish samples has been investigated, using a… Expand
