Electropolymerized phenol derivatives as permselective polymers for biosensor applications
( The Royal Society of Chemistry , 2015 , Article)
Amperometric biosensors are often coated with a polymeric permselective film to avoid electroactive interference by reducing agents present in the target medium. Phenylenediamine and phenol monomers are commonly used to ...
Low electro-synthesis potentials improve permselectivity of polymerized natural phenols in biosensor applications
( Elsevier , 2017 , Article)
First-generation amperometric biosensors are often based on the electro-oxidation of oxidase-generated H2O2. At the applied potential used in most studies, other molecules such as ascorbic acid or dopamine can be oxidized. ...
Fungal and aflatoxin contamination of marketed spices
( Elsevier Ltd. , 2014 , Article)
Fourteen spice samples were collected from local markets in Doha, Qatar, during 2012, and were surveyed for the presence of potentially harmful mycoflora and for contamination with aflatoxins B1, B2, G1, and G2 by ...
Adsorption of ochratoxin A from grape juice by yeast cells immobilised in calcium alginate beads
( Elsevier , 2016 , Article)
Grape juice can be easily contaminated with ochratoxin A (OTA), one of the known mycotoxins with the greatest public health significance. Among the different approaches to decontaminate juice from this mycotoxin, microbiological ...
