Global food and water safety issues have prompted the development of highly sensitive,
specific, and fast analytical techniques for food and water analysis. The electrochemical …

Mycotoxins contamination in both food and feed is inevitable. Mycotoxin toxicity in foodstuff
can occur at very low concentrations necessitating early availability of sensitive and reliable …

Aptamers are molecular recognition elements made of nucleic acids. Diverse synthetic
aptamers have been discovered in a large number of SELEX experiments since 1990. This …

This review discusses the current state of electrochemical biosensors in the determination of
mycotoxins in foods. Mycotoxins are highly toxic secondary metabolites produced by molds …

We report an aptamer-based biosensor for detection of aflatoxin B 1 (AFB 1), a mycotoxin
identified as contaminant in food. The sensor is assembled in a multilayer framework that …

In this article, a novel aptasensor for ochratoxin A (OTA) detection based on a screen-printed
carbon electrode (SPCE) modified with polythionine (PTH) and iridium oxide nanoparticles …

Food safety is a global health objective, and foodborne diseases represent a major crisis in
health. Techniques that are simple and suitable for fast screening to detect and identify …

Environmental contaminants monitoring is one of the key issues in understanding and
managing hazards to human health and ecosystems. In this context, aptamer based …

Nucleic acid aptamers are emerging as useful molecular recognition tools for food safety
monitoring. However, practical and technical challenges limit the number and diversity of …

Heavy metal ion pollution is a severe problem in environmental protection and especially in
human health due to their bioaccumulation in organisms. Mercury (II)(Hg 2+), even at low …
