Abstract: A method for high rate assembly of nanoelements into two-dimensional void patterns on a non-conductive substrate surface utilizes an applied electric field to stabilize against forces resulting from pulling the substrate through the surface of a nanoelement suspension. The electric field contours emanating from a conductive layer in the substrate, covered by an insulating layer, are modified by a patterned photoresist layer, resulting in an increased driving force for nanoelements to migrate from a liquid suspension to voids on a patterned substrate having a non-conductive surface. The method can be used for the production of microscale and nanoscale circuits, sensors, and other electronic devices.

Abstract: Sensors based on single-walled carbon nanotubes (SWNT) are integrated into a microfluidic system outfitted with data processing and wireless transmission capability. The sensors combine the sensitivity, specificity, and miniature size of SWNT-based nanosensors with the flexible fluid handling power of microfluidic “lab on a chip” analytical systems. Methods of integrating the SWNT-based sensor into a microfluidic system are compatible with the delicate nature of the SWNT sensor elements. The sensor devices are capable of continuously and autonomously monitoring and analyzing liquid samples in remote locations, and are applicable to real time water quality monitoring and monitoring of fluids in living systems and environments. The sensor devices and fabrication methods of the invention constitute a platform technology, because the devices can be designed to specifically detect a large number of distinct chemical agents based on the functionalization of the SWNT.

Abstract: Damascene templates have two-dimensionally patterned raised metal features disposed on an underlying conductive layer extending across a substrate. The templates are topographically flat overall, and the patterned conductive features establish micron-scale and nanometer-scale patterns for the assembly of nanoelements into nanoscale circuits and sensors. The templates are made using microfabrication techniques together with chemical mechanical polishing. These templates are compatible with various directed assembly techniques, including electrophoresis, and offer essentially 100% efficient assembly and transfer of nanoelements in a continuous operation cycle. The templates can be repeatedly used for transfer of patterned nanoelements thousands of times with minimal or no damage, and the transfer process involves no intermediate processes between cycles. The assembly and transfer processes employed are carried out at room temperature and pressure and are thus amenable to low cost, high-rate device production.

Abstract: A single-walled carbon nanotube-based micron scale multiplex biosensor is provided that enables the detection of glucose, lactate, and urea. The sensor is based on modification of semiconducting single-walled carbon nanotubes using a linker that non-covalently associates with the nanotubes and covalently couples to an enzyme. Reaction of a physiological substrate with the enzyme results in increased resistance of the nanotubes within the sensor. The sensor is suitable for use in patient monitoring, particularly in a clinical setting. Incorporation of read out electronics and an RF signal generator into the sensor device enables it to communicate to a relay station or remote receiver. Methods are also provided for fabricating the biosensor device and using the device for detection.
