Organophosphates (OPs) widely exist in ecosystem as toxic substances,and it is high desire to develop a sensitive and rapid analytical method in the field.I
In this paper,we report initially a new electrochemical biosensor for picomolar detection of sequence-specific DNA-binding protein using a double-stranded,e
Cr(Ⅵ) ion and some metal ions were found to be able to quench the electrochemilunescence (ECL) of GQDs/S2O8 2- coreactant system.Except for Cr(Ⅵ) ion,the
