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.

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. 鈥淣ow we can start to develop components that speak the body鈥檚 own language,鈥� says Daniel Simon, LOE.

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.

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 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.

Despite surgery and subsequent treatment with chemotherapy and radiation, the majority of patients experience recurrence of malignant brain tumours. Researchers at LiU have shown that an ion pump can be used to treat brain cancer.

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鈥檚 molecules as triggers.
