AbstractA miniaturized potentiometric saxitoxin sensor on graphene nanosheets with incorporated lipid films and Anti‐STX, the natural saxitoxin receptor, immobilized on the stabilized lipid films is described in the present paper. An adequate selectivity for detection over a wide range of toxin concentrations, fast response time of ca.

A comprehensive study on freshwater pufferfish Pao baileyi: profiles of toxin possession, accumulation, and uptake [PDF]
Freshwater pufferfish, primarily belonging to the genus Pao, constitute an important branch in the family Tetraodontidae. Toxic freshwater pufferfish contain saxitoxin (STX) but lack tetrodotoxin (TTX), which is commonly found in marine pufferfish. Here,

Fish detect extremely low levels of marine toxins tetrodotoxin (TTX) and saxitoxin (STX) via the specialized gustatory receptor(s). Physiological and pharmacological studies show that receptor(s) for TTX and STX are distinct from those which detect ...

Artificial Intelligence (AI) in Saxitoxin Research: The Next Frontier for Understanding Marine Dinoflagellate Toxin Biosynthesis and Evolution [PDF]
Saxitoxin (STX) is one of the most potent marine neurotoxins, produced by several species of freshwater cyanobacteria and marine dinoflagellates. Although omics-based approaches have advanced our understanding of STX biosynthesis in recent decades, the ...

Development of a Sandwich-Type sxtA4 Electrochemical Biosensor for Proactive Environmental Monitoring of STX-Producing Microalgae [PDF]
Saxitoxin (STX), produced by certain harmful algal bloom (HAB) species, bioaccumulates through the food chain and can cause paralytic toxicity in humans, potentially resulting in fatal outcomes.

Rapid Detection of Saxitoxin Using a Nucleic Acid Aptamer Biosensor Based on Graphene Oxide as a Fluorescence Quencher [PDF]
Saxitoxin (STX) is a toxin with paralyzing and lethal properties, necessitating the development of a simple analytical method. This study developed a nucleic acid aptamer biosensor using graphene oxide (GO) as a fluorescence quencher for STX detection ...

Transcriptomic insights into polyketides and toxin biosynthesis genes in freshwater dinoflagellates [PDF]
Freshwater dinoflagellates are typically considered non-toxic, and their polyketides and toxin biosynthesis genes are largely unexplored. Here, we generated and analyzed the transcriptome of freshwater dinoflagellate Palatinus apiculatus and compared it ...
