Electrocatalytic self-assembled multilayer structures based on thiolated Fc-DAB dendrimers: Determination of heavy metal ions by enzymatic inhibition
The development of sensitive and rapid inhibition-based biosensors for monitoring trace levels of heavy metals such as lead and copper ions in environmental samples is of high interest. In this work, we describe the fabrication of HRP sensitive peroxide biosensors based on ferrocenyl thiolated DAB d...

| Sumario: | The development of sensitive and rapid inhibition-based biosensors for monitoring trace levels of heavy metals such as lead and copper ions in environmental samples is of high interest. In this work, we describe the fabrication of HRP sensitive peroxide biosensors based on ferrocenyl thiolated DAB dendrimers as bonding-layer between electrodeposited and colloidal gold nanoparticles and compare their electrocatalytic properties with those of thiolated DAB homologues. The complete electrochemical, kinetic and analytical characterization of these new heavy metals’ inhibition-biosensors are investigated |
