The influence of the experimental conditions (glutathione concentration and incubation time and temperature) concerning the covalent immobilization of glutathione via carbodiimide coupling on the behavior of a glutathione modified screen-printed carbon electrode obtained by electrografting is evaluated. The optimized parameters fasten the modification process and improve the performance of the ...

In this study, an electrochemical sensor for the quantification of folic acid with voltam­metric detection in physiological conditions was constructed. For purpose, nickel ferrite (NiFe2O4) nanoparticles were used to modify surface a screen-printed graphite electrode (NiFe2O4/SPGE) and applied determination acid. The modified displays strong response Folic determined electrochemically using dif...
