Abstract

Progress in the application of vertically-aligned carbon nanofibers (VACNF) as parallel subcellular and molecular-scale probes for biological manipulation and monitoring is reported. VACNFs possess many attributes that make them very attractive for implementation as functional, nanoscale features of microfabricated devices. For example, they can be synthesized at precise locations upon a substrate, can be grown many microns long, and feature sharp, nano-dimensioned tips. This, and their needlelike, vertical orientation upon a substrate, makes them particularly attractive as multielement cellular scale probes or as a parallel embodiment of traditional single-point microinjection or microelectrophysiological systems. We will overview our progress with fabricating and characterizing several embodiments of VACNF cell probing systems, which all feature arrays of nanoscale electrochemically-active probing regions at the tips of individually electrically-addressed nanofiber elements. We also overview our techniques of integrating these probing structures with intact cells and how these structures may be used on a massively parallel basis for measurement and control around and within viable cells.
