In paper we describe a technique to purify and segregate carbon nano tubes (CNTs) from the iron impurities to use the CNTs for thin films. After extensive research into a proper and repeatable cleaning process we developed a new method of using bacteria to remove impurities from CNTs. This gives us the ability to manipulate the CNT. We also developed an apparatus based on inkjet technology that deposit the bacteria containing CNT on conductive surfaces such as silicon, plastic, or any other conductive surface. In this way we create a simple way to manipulate the CNTs for the creation of organic LED, Thin Films, or even electronic devices such as transistors using a simple process. Our methods specifically apply to CNTs obtained by the HiPCO process. However, we assume the method can be extended to other cases. We expect this approach will lead to finding novel conductors, structures and thin films for future nano-engineered devices that could be investigated further for use in nano-scale electronics, implants and bio-materials.
