Fabrication of porous reduced GO thin film EGNITE. This involves filtering the GO solution through a porous membrane (1, 2), transferring the deposited film of stacked GO flakes onto a conductive substrate (3), and hydrothermally reducing the aggregate. It consists of making the membrane highly porous and electrically conductive (4) ). credit: natural nanotechnology (2024). DOI: 10.1038/s41565-023-01570-5

Years of research have led to the development of EGNITE (Engineering Graphene for Neural Interfaces), a new type of graphene-based implantable neurotechnology that is flexible, high-resolution, and highly precise.
This study was announced today (January 11th). natural nanotechnology Adds innovative technology to the blossoming landscape of neuroelectronics and brain-computer interfaces.
EGNITE builds on the inventor’s vast experience in carbon nanomaterial manufacturing and medical translation. This innovative technology, based on nanoporous graphene, integrates standard manufacturing processes from the semiconductor industry to assemble graphene microelectrodes just 25 μm in diameter. Graphene microelectrodes exhibit low impedance and high charge injection, properties essential for flexible and efficient neural interfaces.
Preclinical research by various neuroscience and biomedical experts affiliated with ICN2 uses different models for both the central and peripheral nervous systems to record high-fidelity neural signals with great clarity and precision It demonstrated EGNITE’s ability to perform and, more importantly, highly targeted recordings. Neuromodulation. The unique combination of high-fidelity signal recording and precise nerve stimulation provided by EGNITE technology represents a potentially significant advance in neuroelectronic therapy.
This innovative approach addresses a critical gap in neurotechnology, where little material progress has been made over the past two decades. The development of the EGNITE electrode has the potential to place graphene at the forefront of neuroengineering materials.
