Since Carbon Nanotubes (CNT) were discovered in the early 90’s a whole new research field has evolved. CNTs have many properties that make them desirable for the construction of nano-scale Electronics. One area that is receiving increasing attention is the nano-scale thin films. Recently, graphene has been suggested as a thin film candidate for nano-electronics. Our work is focusing on other techniques to realize thin films of CNTs using bacteria. In this work we describe a technique to purify and segregate CNTs from the iron impurities to use the CNTs for thin films. After much research into a proper and repeatable cleaning process we have developed a new method of using bacteria to remove impurities from CNT’s, which also give 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 silicon, plastic, or any other conductive surface, which create a simple way to manipulate the CNT 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 use of HiPCo method of manufacturing the CNTs. However, we think 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.
