An electrochemical immunosensor is developed to determine zearalenone (ZEA) mycotoxin in maize samples. It is based on the use of a composite, which was prepared from anti-ZEA poly-clonal antibody bonded to gold nanoparticles immobilized on multi-walled carbon nanotubes/polyethyleneimine dispersions. Carbon screen printed-electrodes (CSPE) were used in the electrochemical transduction stage. The immunoassay...
Diseases caused by enterotoxicogenic Escherichia coli F4 (K88) (ETEC F4) are a problem in swine production establishments. Due to the high rate of mortality and morbidity of E. coli infections, a rapid and accurate diagnosis is important in order to choose an appropriate treatment to reduce the economic impact. Therefore, an electrochemical magneto-immunosensor (EMI) was developed to detect and quantify...
