Development of electrochemical aptasensor based on gold nanorod and its application for detection of aflatoxin B1 in rice and blood serum sample
Aflatoxins are a group of fungal mycotoxins produced mainly by molds, e.g. Aspergillus flavus and Aspergillus parasiticus. Among Aflatoxins, Aflatoxin B1 (AFB1) is the most toxic. Therefore, there is a prompt need for determination of AFB1 in food products. This paper reports an electrochemical aptasensor for accurate determination of AFB1, which was constructed by the using gold nanorod sensin...
متن کاملIn Vitro Binding Potentials of Bentonite, Yeast Cell Wall and Lactic Acid Bacteria for Aflatoxin B1 and Ochratoxin A
Background: This study intended to assess individual and combined adsorption potentials of three adsorbents (processed bentonite as an inorganic adsorbent, and cell walls of Saccharomyces cerevisiae and of the GG strain of Lactobacillus rhamnosus as organic adsorbents) for aflatoxin B1 and ochratoxin A under in vitro conditions. Methods: This study was conducted in Ferdowsi University of Mashh...
متن کاملTotal Aflatoxin”, “Aflatoxin B1” and “Ochratoxin A” Residues in Wheat Flour Produced in Kurdistan Province-Iran
ABSTRACT Background and objectives: Contamination of food products with mycotoxins is a public health problem. The International Agency for Research on Cancer has identified mycotoxins as hepatotoxic and carcinogenic agents to humans (Group 1). The Kurdistan Province is the ninth largest producer of wheat in Iran. We aimed to determine the level of contamin...
متن کاملFungi and Mycotoxins in Feed Intended for Sows at Different Reproductive Stages in Argentina
The aim of this study was to evaluate fungi and contamination levels of aflatoxin B(1), ochratoxin A, fumonisin B(1), and zearalenone in raw materials and finished feed intended for sows at different reproductive stages. Total fungi, Aspergillus, Penicillium, and Fusarium species occurrence, were examined. Aspergillus flavus, A. niger aggregate spp., and F. verticillioides were the prevalent sp...
متن کاملDEVELOPMENT OF A RAPID AND SENSITIVE RADIOIMMUNOASSAY FOR MEASUREMENT OF AFLATOXIN B 1 IN BIOLOGICAL SAMPLES
Aflatoxin B I (AFB) isa well known hepatocarcinogen in several animal species and probably a causative agent in human hepatocellular carcinoma. Humans are exposed to AFB by ingesting contaminated food. Aflatoxin contamination encountered in human foods is usually at low levels which is difficult to measure by chromatographic methods. Therefore in the present study we have developed an immun...
