Abstract: A method of fabricating a carbon nanotube based device, including forming a trench having a bottom surface and sidewalls on a substrate, selectively depositing a bi-functional compound having two reactive moieties in the trench, wherein a first of the two reactive moieties selectively binds to the bottom surface, converting a second of the two reactive moieties to a diazonium salt; and reacting the diazonium salt with a dispersion of carbon nanotubes to form a carbon nanotube layer bound to the bottom surface of the trench.

Abstract: A drug delivery system includes a substrate, an integrated sensor disposed on the substrate, a drug delivery element disposed on the substrate, and a control unit coupled to the integrated sensor and the drug delivery element. The integrated sensor includes first and second electrodes disposed on a first surface of the substrate. The drug delivery element includes a reservoir disposed on the first surface of the substrate, a thermally active polymer enclosing the reservoir, and a heating coil disposed over the thermally active polymer. The control unit is configured to measure a biological parameter by measuring a voltage difference between the first and second electrodes of the integrated sensor, and to apply a trigger signal to the heating coil of the drug delivery element responsive to the measured biological parameter indicating a designated condition to heat up the thermally active polymer to selectively release a drug from the reservoir.
