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 chip or computer 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 can be used to send current through the nanowire array.

摘要:
A nanoscopic transistor is made by forming an oxide layer on a semiconductor substrate, applying resist, patterning the resist using imprint lithography to form a pattern aligned along a first direction, applying a first ion-masking material over the pattern, selectively lifting it off to leave a first ion mask to form a gate, forming doped regions by implanting a suitable dopant, applying another layer of resist and patterning the second resist layer using imprint lithography to form a second pattern aligned along a second direction, applying a second ion-masking material over the second pattern, selectively lifting it off to leave a second ion mask defined by the second pattern, and forming second doped regions in the substrate by implanting a suitable second dopant selectively in accordance with the second ion mask. The method may be used to make an array of nanoscopic transistors.
