SHORT DESCRIPTION AND USEFUL INFO:
Graphene Gold Platform
In this work, we intentionally perform the electrochemical deposition of gold nanoparticles (AuNPs) onto graphene nanosheets (GN) in order to demonstrate a reliable and a stable approach to immobilize various biomolecules through a noble metal on any graphene based bio-device. Enzymes, antibodies and oligonucleotide immobilisation (DNA fragments, 10-30 bases) onto our graphene-gold nanoparticle platform will be tested with several electrochemical techniques includng Electrochemical Impedance Spectroscopy (EIS) for specific analytes of environmental interest (air pollution, indoor, outdoor) and/or food (mercury speciation, amphetamines, nicotine, PAH) in order to investigate the behavior of a wide range of biomolecules for future applications in the field of label free biosensors.
