3-D nanowire scaffolds let researchers grow tissue around transistors By NEIL SAVAGE / AUGUST 2012
In the article it shows rat brain cells grown in a 3-D nanowire scaffolding interact with electronics. Very impressive!
“The idea was to make nanoelectronics that looks like the extracellular matrix that holds your cells together,” Lieber says. Scientists already use polymer scaffolds intissue engineering to help grow cells to replace damaged tissue in the body. The group, which also includes MIT professor Robert Langer and Harvard Medical School professor Daniel Kohane, wanted to build a functional, 3-D electronic device that could serve the same purpose.
