Sensor mit freistehenden Nanodrähten und Verfahren zur Bestimmung eines Analyts in einer Flüssigkeit

摘要

A sensor device and method for detecting the presence of an analyte (22) in a fluid solution are disclosed. The sensor device system (10) can include a substrate (12) and an array of free-standing nanowires (16) attached to the substrate. The array can include individual free-standing nanowires wherein each of the individual free-standing nanowires have a first end (24) and a second end (26). The first end is attached to the substrate and the second end unattached to the substrate. Such individual free-standing nanowires are configured for electrical communication with other individual free-standing nanowires through the first end. A signal measurement apparatus (38) such as a chip, computer, or coupon, can be electrically coupled to the array of free-standing nanowires for receiving electrical information from the array of free-standing nanowires. In some embodiments a power source (38) can be used to send electrical current through the nanowire array.
