Neuronal cultures advance ‘brain-on-a-chip’ technology
Lawrence Livermore National Laboratory (LLNL) researchers have increased the complexity of neuronal cultures grown on microelectrode arrays, a key step toward more accurately reproducing the cellular composition of the human brain outside the body. As described in a recently published paper in Scientific Reports, an LLNL team led by biomedical scientist Heather Enright…
Machine learning model may perfect 3D nanoprinting
Two-photon lithography (TPL) — a widely used 3D nanoprinting technique that uses laser light to create 3D objects — has shown promise in research applications but has yet to achieve widespread industry acceptance due to limitations on large-scale part production and time-intensive setup. Capable of printing nanoscale features at a very high resolution, TPL uses a laser…
