  • Patent number: 10319537
    Abstract: A method of graphitic petal synthesis includes a step of providing a flexible carbon substrate, such as that including carbon microfibers. The method further includes the step of subjecting flexible carbon substrate to microwave plasma enhanced chemical vapor deposition. The resulting synthesized graphitic petal structure may optionally be coated with PANI.
    Type: Grant
    Filed: February 14, 2014
    Date of Patent: June 11, 2019
    Assignee: Purdue Research Foundation
    Inventors: Jonathan Clay Claussen, Anurag Kumar, Timothy S. Fisher, Ronald G. Reifenberger, Guoping Xiong, David Benjamin Jaroch, David Marshall Porterfield, Rajib Paul

  • Patent number: 8715981
    Abstract: Networks of single-walled carbon nanotubes (SWCNTs) decorated with Au-coated Pd (Au/Pd) nanocubes are employed as electrochemical biosensors that exhibit excellent sensitivity (2.6 mA mM?1 cm?2) and a low estimated detection limit (2.3 nM) at a signal-to-noise ratio of 3 (S/N=3) in the amperometric sensing of hydrogen peroxide. Biofunctionalization of the Au/Pd nanocube-SWCNT biosensor is demonstrated with the selective immobilization of fluorescently labeled streptavidin on the nanocube surfaces via thiol linking. Similarly, glucose oxidase (GOx) is linked to the surface of the nanocubes for amperometric glucose sensing. The exhibited glucose detection limit of 1.3_M (S/N=3) and linear range spanning from 10 ?M to 50 mM substantially surpass other CNT-based biosensors.
