Biological Applications

     Carbon nanotubes (CNTs) are currently regarded as ideal materials for use in a growing range of applications. In addition to their remarkable physical and electrical properties, CNTs have proven to be highly bio-compatible, a fact that has led CNTs to be used for biosensing, molecular delivery, electrochemical detection of biological species, and tissue scaffolding. NanoLab, a recognized leader in nanotube production, is now investing heavily in this promising field.
     We conduct biologically oriented research and develop products, anticipating future demand for solutions in biosensing, molecular delivery, bio-separation and purification, and tissue growth. In order to achieve this, we have established some general techniques for nanotube functionalization, DNA and protein immobilization, nanotube metallization, and photo- and nanolithography of aligned nanotube arrays.

Tissue Scaffolding
     Tissue engineering is poised to revolutionize modern medicine. Many tissues and organs require bio-compatible substrates that can facilitate tissue growth and implantation. Evidence exists to prove that carbon nanotube paper serves as an efficient tissue scaffold. In fact, NASA recently reported success in using "bucky paper" as a growth scaffold in transplanting epithelial cells. NanoLab has developed an improved CNT network scaffold (image at left) that could readily be applied to such biological applications and is in the process of making this product available.

Nanotube Biosensors
     NanoLab's CNTs have already been used as the basis for biosensors [Sotiropoulou, S., Chaniotakis, N. A. Anals of Bioanalytical Chemistry, 375 (2003), 103]. Presently, NanoLab is in the process of developing various CNT-based biosensing devices. One such device will function due to a photonic crystal array of nanotubes.
