Engineering biology is the application of rigorous engineering principles to the design and fabrication of biological components and systems, from modifications of natural systems to new forms of artificial biology. It encompasses the entire innovation ecosystem, from breakthrough synthetic biology research to translation and application.

The cheaper, more sustainable and energy-dense electrode material could pave the way for wider market penetration of this high-power, quick charging electric vehicle technology.
In the study, published in
Advanced Science, teams at Imperial College London and used lignin – a bio-based by-product of the paper industry – to create free-standing electrodes with enhanced energy storage capacity.
The researchers believe this could be a game-changer for existing supercapacitor technology and emphasise the importance of reducing the production cost of carbon-based electrodes and the reliance on critical materials if free-standing supercapacitors are to play a major role in decarbonising transport alon
