Abstract

The paper describes the synthesis of vertically aligned CNTs and the development of magnetic nanotube substrates for biological applications. The vertical alignment of the CNTs on a silicon substrate for the use in biological sensor systems has been explored. The preliminary experiments to determine the binding and growth of biological samples with CNTs have been described. The potential to use the CNTs as electrode for elctrical stimulation is explored. The growth of magnetic nanotubes and the possibility of utilizing them as scaffold for cellular growth is demonstrated. The paper also described the sythesis and development of the magnetic carbon nanotubes, combining the salient features of the CNTs and MNTs. All the nanotubes are optically charaterizd using SEM and TEM techniques. The magentization of the nanotubes are evaluated using the VSM. Cellular binding is determined using SEM and flourescent microscopy images.
