Single‐Walled Carbon Nanotube Polyelectrolyte Multilayers and Freestanding Films as a Biocompatible Platform for Neuroprosthetic Implants

Abstract

Layer-by-layer (LBL) assembly has been used to prepare single-walled carbon nanotube (SWNT) freestanding structures that can be used for implantable devices with unique mechanical and electrical properties (see Figure). The thin LBL membranes prepared are biocompatible and support extensive neurite outgrowth. The stretched fiber-like LBL freestanding films exhibit neuronal guiding. The SWNT structures described may potentially enable connectivity between neurons.
