Organic Bioelectronics

Jonpump version 2. Kretsar och droppar på plastlaminat.
An organic electronic ion pump (OEIP). The device uses electrophoretic transport through thin polymer films to deliver ions, neurotransmitters, plant hormones, and other small charged molecules into living tissue.

Communicating across the biology-technology divide.

Principal investigator: Daniel Simon

jonpump 2015 Animals, plants, and all biological systems communicate in a language of ions and molecules. Modern technology, on the other hand, relies on a language of electrons. With organic electronic materials’ unique properties, we develop “bilingual” tools to bridge this gap.

Organic electronic materials possess a combination of both electronic and ionic/molecular conductivity. They have thus emerged as excellent tools for developing hybrid technologies that effectively interface biological systems with modern electronic technology such as computers and mobile phones – thus the field of organic bioelectronics. 

In the Organic Bioelectronics group at the Laboratory of Organic Electronics, we investigate this transduction between electronic signals and ionic/molecular signals with self-organising in vivo electrode materials, “iontronic” chemical delivery and circuitry, bacteria-electronic interfaces, biosensors, biomimetic systems, and many other areas.  

We aim to elucidate fundamental processes in biochemistry and physiology, as well as develop tools for next-generation therapies, human-machine interfacing, and blurring the border between living and technological systems.

Electrodes grown in the brain

The boundaries between biology and technology are becoming blurred. Researchers at Linköping, Lund, and Gothenburg universities in Sweden have successfully grown electrodes in living tissue using the body’s molecules as triggers.

Accurate drug dosages with proton traps

Researchers at LiU have developed a proton trap that makes organic electronic ion pumps more precise when delivering drugs. In the long term, the ion pumps may help patients with symptoms of neurological diseases.

An electronic signal expands the material by a factor of 100

Researchers at the Laboratory of Organic Electronics have discovered a material that can both increase and reduce its volume when exposed to a weak electrical pulse. In a filter, the researchers can control the size of particles that pass through.
