Detection of Food Contaminants using Nanotechnology - A Mini Review

Abstract

Ingestion of microbial-contaminated food causes severe health issues due to the outburst of serious foodborne diseases. To prevent these situations, sensitive and precise detection of toxins and identification of pathogenic microbes are very important in today’s world. Different types of toxins include natural, chemical, and metal toxins. Based on their origin, natural toxins are classified into biotoxins which are produced by microorganisms (algal, bacteria, fungal), animal toxins, and phytotoxins. Researchers enabled the use of nanomaterials in biosensors, enhancing sensitivity, stability, and specificity. Nanomaterials like gold, silver, carbon nanotubes, graphene, magnetic nanoparticles, and quantum dots were commonly used to develop biosensors. Thus, this mini-review summarizes the old conventional and new analytical methods for detecting a few natural toxins present in different food samples.

Investigation of the role of curcumin against the toxicity induced by bisphenol a on the reproductive system in male rats

“…This can lead to diminished male fertility, including conditions such as cryptorchidism, testicular dysgenesis, and cancer [5]. Animal studies have demonstrated that it also negatively affects sperm quality and disrupts the integration of germ cell nests [6].…”
