Oxford University researchers have made a significant step toward realizing a form of “biological electricity” that could be used in a variety of bioengineering and biomedical applications, including communication with living human cells. The work was published on 28 November in the journal Science.
Iontronic devices are one of the most rapidly-growing and exciting areas in biochemical engineering. Instead of using electricity, these mimic the human brain by transmitting information via ions (charged particles), including sodium, potassium, and calcium ions.
Ultimately, iontronic devices could enable biocompatible, energy-efficient, and highly precise signaling systems, including for drug-delivery.
