An Autonomous Platform for Near Real-Time Surveillance of Harmful Algae and Their Toxins in Dynamic Coastal Shelf Environments

Journal of Marine Science and Engineering, 2021
Efforts to identify in situ the mechanisms underpinning the response of harmful algae to climate change demand frequent observations in dynamic and often difficult to access marine and freshwater environments.

Monitoring the presence of domoic acid in the production areas of bivalve molluscs

Italian Journal of Food Safety, 2016
Algal biotoxins, chemical compounds produced by some microscopic algae, constitute the phytoplankton. The mussels, feeding on phytoplankton, can accumulate these compounds to become themselves toxic.

Phytoplankton Dynamics in the Middle Adriatic Estuary, with a Focus on the Potentially Toxic Genus Pseudo-nitzschia

Journal of Marine Science and Engineering, 2020
The Krka River estuary is a karstic, permanently stratified estuary due to the strong freshwater inflow. It is a special environment in which to study the phytoplankton community, especially because this area is an important aquaculture site. Among other

Co-occurrence of marine and freshwater phycotoxins in oysters, and analysis of possible predictors for management

Toxicon: X, 2023
Oysters (Crassostrea virginica) were screened for 12 phycotoxins over two years in nearshore waters to collect baseline phycotoxin data and to determine prevalence of phycotoxin co-occurrence in the commercially and ecologically-relevant species.

Exploring the Potential of Zero‐Dimensional Carbon Nanomaterials in Photoluminescent, Electrochemiluminescent and Electrochemical Sensors

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

The neuroprotective effects of virally-derived caspase inhibitors p35 and crmA following a necrotic insult

Neurobiology of Disease, 2003
Neuronal excitotoxicity causes energetic impairment and the ensuing cell death has historically been regarded as necrotic. Recent findings, however, indicate that apoptosis may participate in excitotoxicity.

Biosensors for Biotoxins Detection and Monitoring

Advanced Sensor Research, Volume 5, Issue 6, June 2026.
This review examines state‐of‐the‐art biosensing platforms for biotoxin detection, including antibody‐, aptamer‐, CRISPR‐, nanopore‐, whole cells‐ and MIP‐based sensors. It highlights advances in ultra‐sensitive detection, real‐matrix validation in food and water, and multiplexed analysis, and discusses how the integration with machine learning ...

Evaluation of the study carried out by ANSES on the effectiveness of sanitary shucking of queen scallops (Aequipecten opercularis) contaminated by okadaic acid toxins

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract Following a request from the European Commission, EFSA evaluated the effectiveness of sanitary shucking of queen scallops (Aequipecten opercularis) contaminated with okadaic acid (OA) group toxins. Specifically, EFSA was tasked to evaluate a study conducted by the French Agency for Food, Environmental and Occupational Health & Safety (ANSES ...

Improved Detection of Domoic Acid Using Covalently Immobilised Antibody Fragments

Marine Drugs, 2013
Antibody molecules, and antibody fragments in particular, have enormous potential in the development of biosensors for marine monitoring. Conventional immobilisation approaches used in immunoassays typically yield unstable and mostly incorrectly oriented

Fusing Multi‐ and Hyperspectral Satellite Data for Harmful Algal Bloom Monitoring With Self‐Supervised and Hierarchical Deep Learning

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract We present a self‐supervised machine learning framework for detecting and mapping the severity and speciation of harmful algal blooms (HABs) using multi‐sensor satellite data. By fusing reflectance data from operational polar‐orbiting satellite‐based instruments (VIIRS, MODIS, OLCI, and OCI) with TROPOMI solar‐induced fluorescence (SIF), our ...
