Aptamers Based Biosensors for Disease Detection
In the fabrication of biosensor, biorecognition elements or bioreceptorplay an important role. Bioreceptor is a biological molecular species (e.g. antibody, enzyme or nucleic acid) or a living biological system (e.g. cells, tissues or whole organisms) that has capability to recognize a target or substrate (analyte) molecules [1]. Bio-recognition elements have unique profile that helps in provid...
متن کاملUse of biosensors for the detection of marine toxins
Increasing occurrences of harmful algal blooms (HABs) in the ocean are a major concern for countries around the globe, and with strong links between HABs and climate change and eutrophication, the occurrences are only set to increase. Of particular concern with regard to HABs is the presence of toxin-producing algae. Six major marine biotoxin groups are associated with HABs. Ingestion of such t...
متن کاملAlternative Methods for the Detection of Emerging Marine Toxins: Biosensors, Biochemical Assays and Cell-Based Assays
The emergence of marine toxins in water and seafood may have a considerable impact on public health. Although the tendency in Europe is to consolidate, when possible, official reference methods based on instrumental analysis, the development of alternative or complementary methods providing functional or toxicological information may provide advantages in terms of risk identification, but also ...
متن کاملBiosensors to detect marine toxins: Assessing seafood safety.
This article describes the different types of marine toxins and their toxic effects, and reviews the bio/analytical techniques for their detection, putting special emphasis to biosensors. Important health concerns have recently appeared around shellfish (diarrheic, paralytic, amnesic, neurologic and azaspiracid) and fish (ciguatera and puffer) poisonings produced by different types of phycotoxi...
متن کاملIllnesses caused by marine toxins.
Marine toxins are produced by algae or bacteria and are concentrated in contaminated seafood. Substantial increases in seafood consumption in recent years, together with globalization of the seafood trade, have increased potential exposure to these agents. Marine toxins produce neurological, gastrointestinal, and cardiovascular syndromes, some of which result in high mortality and long-term mor...
