Nanomaterial-based biosensors for detection of pathogenic virus
2020
Viruses are real menace to human safety that cause devastating viral disease. The high prevalence of these diseases is due to improper detecting tools. Therefore, there is a remarkable demand to identify viruses in a fast, selective and accurate way. Several biosensors have been designed and commercialized for detection of pathogenic viruses. However, they present many challenges. Nanotechnology overcomes these challenges and performs direct detection of molecular targets in real time. In this overview, studies concerning nanotechnology-based biosensors for pathogenic virus detection have been summarized, paying special attention to biosensors based on graphene oxide, silica, carbon nanotub…
Recent advances in Nanomaterial-mediated Bio and immune sensors for detection of aflatoxin in food products
2017
Abstract Aflatoxin is the most harmful mycotoxin which is ubiquitous in foods and agricultural supplies. Since the health of human population is largely determined by the condition of food-producing, contaminated foods and agricultural supplies with aflatoxin can put the safety of people in jeopardy and lead to some fatal disease. In 2003 estimated the annual cost of aflatoxin contamination in the U.S. at about $500 million strong concern for human life. There are a great demand for development of rapid, sensitive and specific methods for detection of aflatoxin at trace levels. The purpose of this review is limited to novel aflatoxin biosensors, paying special attention to those based on th…
Nano-materials for use in sensing of salmonella infections: Recent advances
2016
Salmonella infectious diseases spreading every day through food have become a life-threatening problem for millions of people and growing menace to society. Health expert's estimate that the yearly cost of all the food borne diseases is approximately $5-6 billion. Traditional methodologies for salmonella analysis provide high reliability and very low limits of detection. Among them immunoassays and Nucleic acid-based assays provide results within 24h, but they are expensive, tedious and time consuming. So, there is an urgent need for development of rapid, robust and cost-effective alternative technologies for real-time monitoring of salmonella. Several biosensors have been designed and comm…
