Grand challenges such as the fabrication of sensing devices for early diagnosis of cancer and detection of food/water contamination can only be addressed with concerted efforts in multidisciplinary research. Selected problems within the above challenges will be tackled in this Project by a multiinstitutional team of physicists, chemists, engineers, medical doctors and computer scientists,…

A modern and innovative concept concerning the energy conversion from solar sources is the use of a hybrid bio-photo-electrochemical cell, where biomolecules and/or microorganisms works cooperatively in the faradaic processes. In this system, there is the integration of the conversion of solar energy into electrical energy through photoelectrochemical cells and of chemical energy into ele…
Carbon electrodes are used in most configurations of biofuels (BC) and organic batteries (OB) because they are stable and have low electrical resistance, leading to a considerable chemical and electrochemical long-term-stability. However, for both BC and OB, the structural heterogeneities of the surface and the presence of defects influence the electron transfer kinetics. In this project,…
Nowadays, miniaturization of biofuel cells (BFCs) is the biggest challenge in bioelectronics, which is directly dependent on obtaining stable and efficient enzymatic bioelectrodes. Our Group has proposed that electrodes based on individual graphene sheets, as well as flexible carbon fibers (FCFs), produce the most efficient bioelectrodes reported so far, these being applied in implantabl…
This Project will bring together four research groups from distinct institutions in order to investigate biologically-relevant nanostructured films, focusing on three topics: i) use of Langmuir monolayers, Langmuir-Blodgett (LB) films and vesicles as cell membrane models; ii) biosensors; and iii) single molecule detection (SMD). The films will be fabricated with the LB and layer-by-layer …

The preparation of biomolecule-nanostructure bioconjugates is a crucial step in the development of lateral flow immunoassays. Besides the high cost of reagents and biomolecules (e.g., proteins and monoclonal antibodies), the conjugation process between them and the metallic nanoparticles (MNPs) involves several experimental steps that require a lot of time, as in the case of the passive a…
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, i…
The use of enzymes to reduce CO2 and N2 for the bioelectrosynthesis of value-added products is a promising alternative to replace high-cost synthetic catalysts. For this purpose, interesting results have been obtained with the use of EcFDH-H and Mo-Fe nitrogenase enzymes immobilized on electrode surfaces. However, the bioelectrocatalytic and charge transfer mechanisms of these enzymes hav…

Some subjects which have not yet been studied or not clarified in the bioelectrochemistry field have an immediate impact on the development and use of energy bioconversion and fuel bioelectrosynthesis technologies. They include: halide inhibition of the multi-copper oxidases enzymatic activity towards the molecular oxygen reduction reaction and the mechanism of the reverse reaction (H2O o…
Microorganisms, biomolecules and biomembranes are usually immobilized on solid surfaces (gold, silicon, quartz, glass, carbon, nanoparticles substrates, etc.) when it is intended to study and / or apply them in biotechnology. This includes the use of fungi and bacteria in bioelectrode of biofuel cells, enzymes in biosensors, membranes in organ-on-a-chip, cell culture in microfluidic syste…
In cellular respiration there are two moving components that are part of the electron transport chain: ubiquinone (Coenzyme Q10) that connects Complex I to II and III, and cytochrome C that connects Complex III to IV. These components are in a viscous medium (inner mitochondrial membrane) with controlled pH and show E1/2 H -400 mV (Ag/AgCl, pH H 7.0) and E1/2 H 200 mV (Ag/AgCl, pH H 7.0),…

Concerns about environmental problems caused by fossil fuels and the continuous energetic crisis have pushed up the interests for renewable energy sources, such as wind, tide, and sunlight. However, to meet the high energy demand of the society, the photovoltaic and wind electricity should be storage in batteries, because of the inherent intermittency of these renewable sources. Redox flo…
Redox enzymes displayed on microbial cell surfaces can exhibit improved stability and activity when compared to the purified enzymes. These features represent great advances in overcoming most limitations for practical application of some large-scale enzyme-based electrochemical systems, such as enzymatic fuel cells and bioelectrosynthesis systems. However, achieving high biocatalyst load…
Redox flow batteries (RFBs) are systems that use redox species to store and generate electrical energy. A RFB should be safe and environmentally friendly and have a high energy density, long lifetime, small size, light weight, and low cost. However, to date, no RFB has achieved all of these criteria. Vanadium RFBs are currently the most technologically established RFB system, but this typ…
The first evidence of charge transfer (CT) mediated by DNA molecules was observed experimentally in 1993, based on oxidative processes, in which a metal complex has been linked to the DNA molecule through one of their bases. Since then, the mechanisms of CT in DNA and RNA have been investigated by several research groups. Based on its structure, DNA holds great promise as a medium for cha…
The possibility to probe small quantities of molecules has taken to new dimension of electrochemical devices in the last decade with the development of micro and nanomanipulation techniques. The development of these techniques has been permitting the manipulation of small quantities and/or individual materials to study events at atomic and molecular level. Regards the manipulation of mate…
