Main research activities/topics/projects

1. Investigation of the electrical properties of nanocomposites based on graphene derivatives and metallic nanoparticles (NPs) as a function of the composition, concentration, and architecture of the hybrid material. Here, we will explore impedance spectroscopy and characterizations using direct current to understand the influence of each parameter on the device performance envisaging biosensing applications.

2. Fabrication and improvement of electrolyte-gated transistors exploiting graphene derivatives as the semiconductor material of the channel. The investigation of the conductivity and mobility mechanisms will also be carried out concerning the incorporation of metallic NPs. We aim to optimize charge transport in these devices to understand the effect of NPs on biosensor performance. Moreover, it is possible to explore the surface of NPs to
promote specific binding with the analytes. The systematic investigation of these systems will enable the development of methods for producing optimized devices.
