Researchers have developed a miniature, biocompatible power source inspired by electric eels that can directly stimulate human nerve cells. This innovation has potential applications in drug delivery, wound healing, and bio-hybrid devices.have achieved a major advancement toward realizing miniature bio-integrated devices, capable of directly stimulating cells.
The power source is turned on by cooling the structure to 4°C and changing the surrounding medium: this disrupts the lipid bilayers and causes the droplets to form a continuous hydrogel. This allows the ions to move through the conductive hydrogel, from the high-salt droplets at the two ends to the low-salt droplet in the middle.
The research team then demonstrated how living cells could be attached to one end of the device so that their activity could be directly regulated by the ionic current. The team attached the device to droplets containing human neural progenitor cells, which had been stained with a fluorescent dye to indicate their activity. When the power source was turned on, time-lapse recording demonstrated waves of intercellular calcium signaling in the neurons, induced by the local ionic current.
