  • Patent number: 8882977
    Abstract: Glucose and ATP biosensors have important applications in diagnostics and research. Combining single-walled carbon nanotubes (SWCNTs) with Pt nanoparticles can significantly enhance the performance of electrochemical biosensors. This disclosure illustrates the use of single-stranded DNA (ssDNA) to modify SWCNTs to increase SWCNT solubility in water. Multiple embodiments with this configuration allows for exploration of new schemes of combining ssDNASWCNT and Pt black in aqueous media systems. These embodiments resulted in a nanocomposite with enhanced biosensor performance. The ssDNA-SWCNT/Pt black nanocomposite constructed by a layered scheme proved most effective in terms of biosensor activity. The key feature of this structure and method of use is the exploitation of ssDNASWCNTs as molecular templates for Pt black electrodeposition. Glucose and ATP microbiosensors fabricated utilizing this structure and method of use exhibited high sensitivity, wide linear range and low limit of detection.

  • Publication number: 20130260136
    Abstract: Disclosed herein are solvent free, dry coating processes for applying a layered material such as graphene, nanoplate graphite, etc., to a substrate. The applied layered material is devoid of any dispersant and substantially uniform in thickness. Generally, a layered material precursor composition is mixed with a milling medium so that the milling medium is coated with the layered material. The substrate is then contacted with the coated milling medium. The layered material on the milling medium transfers to the substrate to form a coating on the substrate. Such processes may be especially useful for applying conductive films onto a polymeric substrate without the need for additives such as a surfactant or a polymeric binder.
