Electrochemical biosensor for the dual detection of Gambierdiscus australes and Gambierdiscus excentricus in field samples. First report of G. excentricus in the Balearic Islands
(Elsevier, 2021-10-13)
Several genera of marine dinoflagellates are known to produce bioactive compounds that affect human health. Among them, Gambierdiscus and Fukuyoa stand out for their ability to produce several toxins, ...
Immobilisation of Neuro-2a cells on electrodes and electrochemical detection of MTT formazan crystals to assess their viability
(Elsevier, 2022-09-24)
Marine toxins are potent toxic compounds that may reach humans and poison them. Therefore, their detection in seafood is crucial to prevent intoxication cases. Colorimetric cell-based assays (CBAs) have ...
Detection of Gambierdiscus and Fukuyoa single cells using recombinase polymerase amplification combined with a sandwich hybridization assay
(Springer, 2021-04-10)
Dinoflagellates of the genera Gambierdiscus and Fukuyoa are known to produce several bioactive compounds including the potent neurotoxic ciguatoxins (CTXs) which are able to accumulate in fish and through ...
Detection of Ostreopsis cf. ovata in environmental samples using an electrochemical DNA-based biosensor
(Elsevier, 2019-06-28)
Ostreopsis cf. ovata is a benthic microalga distributed in tropical and temperate regions worldwide which produces palytoxins (PlTXs). Herein, an electrochemical biosensor for the detection of this toxic ...
Cyclodextrin polymer clean-up method for the detection of ciguatoxins in fish with cell-based assays
(Elsevier, 2022-09-13)
Ciguatoxins (CTXs) are marine toxins produced by microalgae of the genera Gambierdiscus and Fukuyoa, which are transferred through the food webs, reaching humans and causing a poisoning known as ciguatera. ...
A smartphone-controlled amperometric immunosensor for the detection of Pacific ciguatoxins in fish
(Elsevier, 2021-12-02)
Ciguatoxins (CTXs) are marine neurotoxins produced by microalgae of the genera Gambierdiscus and Fukuyoa. CTXs may reach humans through food webs and cause ciguatera fish poisoning (CFP). An immunosensor ...
β-cyclodextrin polymer as tetrodotoxins scavenger in oyster extracts
(Elsevier, 2024-04-16)
Tetrodotoxins (TTXs) are potent marine neurotoxins involved in poisoning cases in humans after consumption of some marine organisms. A cell-based assay (CBA) providing toxicological information is a ...
Self-assembled monolayer-based immunoassays for okadaic acid detection in seawater as monitoring tools
(Elsevier, 2017-11-14)
Rapid and cost-effective methods to monitor the presence of diarrhetic shellfish poisoning (DSP) toxins in seawater samples in an easy and reliable manner are required to protect human health and avoid ...
Detection and quantification of the toxic marine microalgae Karlodinium veneficum and Karlodinium armiger using recombinase polymerase amplification and enzyme-linked oligonucleotide assay
(Elsevier, 2018-07-28)
Karlodinium is a dinoflagellate responsible for fish-killing events worldwide. In Alfacs Bay (NW Mediterranean Sea), the presence of two Karlodinium species (K. veneficum and K. armiger) with different ...
Development and validation of a maleimide-based enzyme-linked immunosorbent assay for the detection of tetrodotoxin in oysters and mussels
(Elsevier, 2017-08-18)
The recent detection of tetrodotoxins (TTXs) in puffer fish and shellfish in Europe highlights the necessity to monitor the levels of TTXs in seafood by rapid, specific, sensitive and reliable methods ...
