Selenocystine modified screen-printed electrode as an alternative sensor for the voltammetric determination of metal ions

A novel selenium based screen-printed electrode was developed based on the immobilization of selenocystine on aryl diazonium salt monolayers anchored to a carbon-nanofiber screen-printed electrode support (SeCyst- SPCNFE). SeCyst-SPCNFE was analytically compared to a screen-printed carbon nanofiber...
