21_37/2009Neural Electrodes: Interfacing Conducting Polymer Nanotubes with the Central Nervous System: Chronic Neural Recording using Poly(3,4-ethylenedioxythiophene) Nanotubes (Adv. Mater. 37/2009)

Microelectrodes implanted in the brain are increasingly being used to treat neurological disorders. However, robust and reliable chronic application of neural electrodes remains a challenge. Mohammed Reza Abidian and co-workers report on p. 3764 the use of conducting polymer nanotubes as highly selective neural interfaces for chronic neural recordings at the microscale. The quality of neuronal spike recordings was significantly improved relative to comparably sized metal electrode sites, primarily through a reduced noise level amidst maintained spike amplitudes.
