New publication: Nanostructured platinum grass enables superior impedance reduction for neural microelectrodes

The coating provides an impedance that is considerably lower than for other known materials such as IrOx or PEDOT. Given the simplicity and efficiency of the coating method, and the outstanding electrochemical surface enlargement provided thereby, we believe Pt-nanograss comprises a valuable contribution to the community of neural interfaces.
