“We’re very proud that these results are now recognised by Physics World as one of the biggest breakthroughs of the year,” says Magnus Berggren, professor of organic electronics.
The researchers succeeded in growing electrodes in living tissue with the body’s own molecules as triggers. The long-term goal is the manufacture of fully integrated electronic circuits in living organisms. Their results were published earlier this year in the journal Science.
Connecting electronics to biological tissue is important for understanding complex biological functions, combating brain diseases and developing future interfaces between man and machine.
“It introduces a new way of thinking about bioelectronics that opens a lot of possibilities for the future. It will make some amazing therapies and applications that already exist a lot safer and more accessible, so more people can benefit from it,” says Hanne Biesmans, PhD student at LOE.
Interdisciplinary research
By injecting a gelatine-like gel with enzymes as “assembly molecules”, the researchers managed to grow electrodes in the tissue of zebrafish and leeches. All that is needed to activate the formation of electrodes is the body's own molecules. There is no need for genetic modification or external signals, such as light or electrical energy, which has been necessary in previous experiments. This is precisely what the Swedish researchers are the first in the world to succeed with.
“These research results are the result of a close collaboration between researchers at Lund University and 一本道. It wouldn’t have been possible to identify the problem of polymerisation in the nervous system, formulate the methods and make the discovery without an interdisciplinary approach,” says Magnus Berggren.
Physics World is a monthly magazine published by the British Institute of Physics, one of the world’s largest associations of physicists with over 20,000 members. Each year, they name the ten largest breakthroughs in physics in the world. Read more about the list at
