Welcome to Crespilho’s Group

In the Crespilho’s group, we study the chemical and physical properties of redox systems and redox biomolecules on solid surfaces. Also, we are interested in the bioelectrochemical and technological implications of those properties. Our current research is focused in three majors’ areas:

Energy and Bioenergy

Biological Fuel Cells, Biobatteries and Organic Batteries.

Fundamental Bioelectrochemistry

Modeling of Charge-Transfer Mechanisms of Enzymes, Bio-Electrocatalysis, Electrodes Materials and In Situ and Operando  techniques.

Bioelectronics Devices

Biosensors and Emerging Biomimetic Materials.
