UTILIZATION OF NANOWIRES IN CHEMICAL AND BIOLOGICAL ANALYSIS

摘要

The invention provides devices and methods for ultrasensitive chemical and biological analysis. The method is based on end derivatized nanowires (104). After affinity or supramolecular binding these nanowires (104) can be detected either optically or electronically in a certain location that is specific for a given analyte (108). Nanowires can carry very large number of optically detectable groups. Alternatively, they can close an electronic circuitry (102, 103, 109), and the change in an electric property (110) of that circuitry is detected.
