Abstract

The Bioelectrochemistry and Interfaces Group coordinated by Professor Frank Crespilho has an excellent track record in the fabrication of bioelectrodes based on the modification and engineering of carbon materials with various biomolecules, including enzymes, coenzymes, and single-cell organisms, seeking practical applications in biodevices, biofuel cells, and biosensors. More recently, it has extended the expertise in the field towards the implementation of graphene and Single Entity Electrochemistry (SEE). Promising outcomes are expected in the field through the elaboration of this project, in which Van der Waals surfaces on top of a graphene monolayer will be established. The new surface with the inherent properties will bring a new trend in biosensing applications alongside new ideas and concepts produced in interface science. The group is offering a postdoctoral position, with FAPESP scholarship (linked thematic project 2018/22214-6), with a minimum period of two years, for Chemists, with strong knowledge in electrochemistry and desirable knowledge in spectroscopy, microscopy, in-situ techniques, enzymatic immobilization, graphene transfer and preparation of bioelectrodes. Additionally, the candidate is expected to develop projects with a focus on coupling the Scanning Tunneling Microscopy (STM) and electrochemical techniques, to understand interfacial phenomena in bio-devices with Van der Waals surfaces.
