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…
Preparation of Carbon-14 Labeled 2-(2-mercaptoacetamido)-3-phenylpropanoic Acid as Metallo-beta-lactamases Inhibitor (MBLI), for Coadministration wit…
2019
Aim and Objective: Bacteria could become resistant to β-lactam antibiotics through production of β- lactamase enzymes like metallo-β-lactamase. 2-(2-mercaptoacetamido)-3-phenylpropanoic acid was reported as a model inhibitor for this enzyme. In order to elucidate the mechanism of action in the body’s internal environment, preparation of a labeled version of 2-(2-mercaptoacetamido)-3-phenylpropanoic acid finds importance. In this regard, we report a convenient synthetic pathway for preparation of carbon-14 labeled 2-(2- mercaptoacetamido)-3-phenylpropanoic acid. Materials and Methods: This study was initiated by using non-radioactive materials. Then, necessary characterization was performed…
Development of biosensors for detection of alpha-fetoprotein: As a major biomarker for hepatocellular carcinoma
2020
Abstract Alpha-fetoprotein as a multifunctional glycoprotein with a dual regulatory role in cancer and fetal activities is belonging to an albuminoid gene family. Due to important biological activities of alpha-fetoprotein in the adjustment of cancer, the level of this biomarker, majorly in liver carcinomas, abnormally is elevated. Also, the probability of high-risk or low-risk patients for chromosomal abnormalities can be identified by the serum level of alpha-fetoprotein. The detection of biomarkers possesses an important role in prognosis and early diagnosis of cancer and other diseases. So, the development of accurate and sensitive methods for measurement of alpha-fetoprotein is of grea…
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…
Recent advances on nanomaterial based electrochemical and optical aptasensors for detection of cancer biomarkers
2018
Abstract Cancer is a real menace to all societies globally since it is the leading cause of premature mortality in men and women. The incidence of malignancies is enhancing as a result of plenty factors. Physically and economically concerns that occur in cancers patients cannot be neglected. However, current diagnostic methods and cure duration do not fulfill patients requirements. Therefore, it is essential to detect and diagnose cancer biomarkers as soon as possible and overcome the current burdens. Novel aptasensors is emerging as one of the most promising strategies for early recognition of cancer. Aptamers an artificial DNA or RNA sequences, possess plenty of merits such as easy produc…
Recent progress in optical and electrochemical biosensors for sensing of Clostridium botulinum neurotoxin
2018
Abstract Botulinum toxin is a neurotoxic protein which produced from Clostridium botulinum and related species and it block acetylcholine release from presynaptic nerve terminals at the neuromuscular junctions. This toxin is life threatening for millions of people and growing menace to society since causing human botulism. Enzymatic activity of Botulinum neurotoxin within the cell made it hazardous and lead to flaccid paralysis. However, there isn't any reliable and precise remedy for this toxin. Therefore, there is an urgent need for early detection of this toxin in a fast and meticulous way with a robust and cost-effective relationship for real-time monitoring of Botulinum neurotoxin. Sev…
