Mechanistic Insights into Cyanobacterial Exoelectrogenesis and Its Biotechnological Applications

The growing global demand for energy, coupled with the urgent need for sustainable production methods, has directed researchers toward biohybrid solar cells. Systems that harness photosynthetic microorganisms such as cyanobacteria in place of synthetic materials to generate electricity. During photosynthesis, cyanobacteria naturally release electrons into their surrounding environment; by interfacing these microorganisms with an electrode, the released electrons can be captured and converted into usable power. My PhD project seeks to leverage state-of-the-art analytical techniques, including surface-enhanced Raman scattering, to unravel the fundamental mechanisms behind this phenomenon, specifically, why and how cyanobacteria expel these energetic electrons. Gaining such mechanistic insight will not only enable us to enhance the efficiency of biohybrid solar cells, but also deepen our broader understanding of cyanobacterial photosynthesis itself.

Who or what inspired you to pursue your research interests?

I have always been fascinated by how nature solves complex problems with elegant efficiency. Photosynthesis is a prime example. it not only sustains life but also provides a blueprint for sustainable power generation in the face of rising CO₂ emissions and global warming. Seeing that cyanobacteria can naturally generate clean electricity fuelled my curiosity and drew me to the field of biohybrid solar cells. Dedicating my PhD to this vital area allows me to bring together my background in analytical chemistry and nanotechnology to tackle key challenges in the field, while also expanding my knowledge into exciting new domains such as sustainability and biotechnology.
