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.

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.
