The development of an international team of scientists will allow us to study the work of individual cells and then create devices for connecting the brain with the machine. The main difference from analogues is that the activity-reading probe does not damage cells.

Reading the electrical activity of cells is at the heart of many biomedical procedures, such as brain mapping and neuroprosthetics. For the further development of this direction, it is very important to develop new non-invasive tools for studying electrophysiological reactions.

An international team of researchers from the UK, USA and South Korea presented their approach to solving the problem. According to a press release from the University of Surrey, Ultra-small nanoprobes could be a leap forward in high-resolution human-machine interfaces, scientists have developed nanoscale probes to register electrical activity inside individual cells.

U-shaped nanoelectrodes can register electrical vibrations inside a neuron or cardiomyocyte without damaging them. These devices are 100 times smaller than modern analogues, which kill the cell after recording – VM.

Experiments have confirmed that the devices do an excellent job of collecting data on the internal electrophysiology of heart cells and neurons. Unlike analogues, they do not violate the internal structure of cells. The authors of the development are confident that it will allow you to learn more about the work of neurons and muscles. In addition, similar devices can form the basis of neural interfaces that provide communication between the brain and technology.

Article by Zhao et al. Scalable ultrasmall three-dimensional nanowire transistor probes for intracellular recording is published in the journal Nature Nanotechnology – VM.
