    • 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). an 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.
    • 本文所述的基于纳米管的横向流动测试装置是基于侧向流动的诊断装置,其使用单壁碳纳米管碎片阵列作为传感器,以超低浓度(低于皮质每毫升)检测生物标志物。 该设备由以下组件组成:(1)。 横向流动条,其通常由层合有共轭/样品垫,硝酸纤维素膜,芯吸垫(2)的背衬膜组成。 与作为测试线固定在侧流装置的膜上的与抗体结合的单壁碳纳米管阵列,(3)。 成对的微电极安装在磁带盒的顶部,(4)。 保持横向流动条的盒。 该装置可用于生物标志物检测的临床环境。

    • 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.
