Abstract
A sensor device and method for detecting the presence of an analyte in a fluid solution are disclosed. The sensor device system can comprise a substrate and an array of free-standing nanowires attached to the substrate. The array can include individual free-standing nanowires wherein each of the individual free-standing nanowires have a first end and a second end. The first end can, in some embodiments, be 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 can be electrically coupled to the array of free-standing nanowires for receiving electrical information from the array of free-standing nanowires.
