  • Patent number: 11131668
    Abstract: Nanotube based lateral flow test device described herein is a lateral flow based diagnostic device, which uses arrays of fragments of single wall carbon nanotubes as sensor to detect the biomarkers at ultralow concentration (below picogram per milliliter). The device is consisted of the following components: (1) a lateral flow strip which typically is consisted of a backing film laminated with conjugate/sample pads, nitrocellulose membrane, wicking pad, (2) the arrays of single wall carbon nanotube conjugate with antibody which is immobilized on the membrane of the lateral flow device as the test line, (3) pairs of micro-electrode are installed on top part of the cassette, (4) a cassette which holds the lateral flow strip. The device can be used in clinical environments for biomarker detection.

  • Publication number: 20060029586
    Abstract: The invention provides bioconjugates of the formula: in which A is an active agent comprising an active hydroxy or amino functionality and B is a biopolymer comprising an active hydroxy or amino functionality, and X1 and X2 are independently N or O, and R is substituted alkyl or unsubstituted alkyl or unsubstituted or substituted heteroalkyl from 1 to about 30 atoms in length. The biopolymer may for instance be a transport protein or an antibody directed to a transport protein (e.g., a p97 protein or antibody thereto). The active agent may be a therapeutic agent such as a chemotherapeutic agent or an antineoplastic agent or an enzyme. The bioconjugates find therapeutic usages according to the therapeutic indications of the active agent. Methods of making the bioconjugates and bifunctional isocyanate cross linking reagents of use in making such bioconjugates are provided.
