Abstract

This paper describes the distinct properties of carbon nanotubes, and their use for biomedical applications. An innovative architecture for medical use of nanorobots are proposed as an advanced and precise tool for brain aneurysm instrumentation as nanorobots. The nanotubes include their nanometer diameter (∼0.4 nm to 3 nm (single walls carbon nanotubes - SWCNTs) and ∼1.4 nm to 100 nm (multi walls carbon nanotubes - MWNTs), length of several micrometers (up to centimeters), large aspect ratio (10-1000). The columnar structure of multi walls carbon nanotubes (MWCNT) is responsable for the special properties. In this paper, the controlled activity of MWCNT was studied at room temperature on dissociated cortical cultures from mice which supported a cerebral aneurism. Neurons and glial cells incubated for several days with this nanotube yielded to some connections between the islands are clearly apparent and interconnected networks are formed following the exact pattern of the MWCNT (nanotube) templates. The bridging consists either of an axon or bundles of axons and dendrites. Three days after incubation with MWCNT, show that cells first aggregate at the MWCNT islands. As they complete this step axons and dendrites begin to form and to build connections.
