Researchers at LiU have developed a type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. The technique can provide important insights into how individual braincells are affected.

When low doses of cancer drugs are administered continuously near malignant brain tumours using so-called iontronic technology, cancer cell growth drastically decreases. This is demonstrated in experiments with bird embryos.

Researchers at LiU have developed a small device that both detects the initial signal of an epileptic attack and doses a substance that effectively stops it. All this takes place where the signal arises.

With a microfabricated ion pump ions can be sent to nerve or muscle cells at the speed of the nervous system and with a precision of a single cell. “Now we can start to develop components that speak the body’s own language,” says Daniel Simon, LOE.

A supercapacitor has been constructed in a plant for the first time. The plant, a rose, can be charged and discharged hundreds of times. This breakthrough is the result of research at the Laboratory of Organic Electronics.

A drug delivery ion pump in organic electronics also works in plants. Researchers from the Laboratory of Organic Electronics at LiU and the Umeå Plant Science Centre have used such an ion pump to control the root growth of a small flowering plant.

Using semi-conductive polymers, both analog and digital electronic circuits can be created inside living flowers, bushes and trees, as researchers at Laboratory for Organic Electronics have shown. The results are being published in Science Advances.

Scientists at LiU’s Laboratory of Organic Electronics have developed an organic transistor that they can use to measure and study in fine detail a phenomenon known as extracellular electron transfer in which bacteria release electrons.

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.

Researchers at the Laboratory of Organic Electronics have developed a method that increases the signal strength from microbial electrochemical cells by up to twenty times. The secret is a film with an embedded bacterium: Shewanella oneidensis.
