Detection of Ciguatoxins and Tetrodotoxins in Seafood with Biosensors and Other Smart Bioanalytical Systems
(MDPI, 2023-05-18)
The emergence of marine toxins such as ciguatoxins (CTXs) and tetrodotoxins (TTXs) in non-endemic regions may pose a serious food safety threat and public health concern if proper control measures are ...
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 ...
Automated Patch Clamp for the Detection of Tetrodotoxin in Pufferfish Samples
(MDPI, 2024-04-15)
Tetrodotoxin (TTX) is a marine toxin responsible for many intoxications around the world. Its presence in some pufferfish species and, as recently reported, in shellfish, poses a serious health concern. ...
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 ...
Detection of azaspiracids in mussels using electrochemical immunosensors for fast screening in monitoring programs
(Elsevier, 2018-02-06)
Given the widespread occurrence of azaspiracids (AZAs), it is clearly necessary to advance in simple and low-cost methods for the rapid detection of these marine toxins in order to protect seafood ...
