High-performance immunosensor for urine albumin using hybrid architectures of ZnO nanowire/carbon nanotube.

In this work, the authors reported the hybrid architecture of carbon nanotube (CNT)-zinc oxide (ZnO) nanowire as a multi-functional probe in amperometric immunosensor for the detection of urine albumin. Low-cost substrate such as glass is possible because of novel low-temperature growth process of CNT/ZnO nanowires as a multi-function electrode in this sensor. Based on Schottky like behaviour this structure exhibit excellent high current density to achieve higher performance.
