    Abstract: A unique ID using optically visible carbon nanotubes with nanocrystal decoration is provided. In one aspect, a method for creating a unique ID includes: providing a substrate having an array of trenches; randomly placing carbon nanotubes throughout the array such that each trench either contains a carbon nanotube or does not, wherein the random placement of the carbon nanotubes throughout the array of trenches includes code information that forms the unique ID; and coating the carbon nanotubes with optically visible nanocrystals. A unique ID and authentication method using the unique ID are also provided.

    Abstract: Structures and methods that include selective electrostatic placement based on a dipole-to-dipole interaction of electron-rich carbon nanotubes onto an electron-deficient pre-patterned surface. The structure includes a substrate with a first surface having a first isoelectric point and at least one additional surface having a second isoelectric point. A self-assembled monolayer is selectively formed on the first surface and includes an electron deficient compound including a deprotonated pendant hydroxamic acid or a pendant phosphonic acid group or a pendant catechol group bound to the first surface. An organic solvent can be used to deposit the electron rich carbon nanotubes on the self-assembled monolayer.

    Abstract: Frequency division multiplexing-based techniques for FET-based sensor arrays are provided. In one aspect, a sensor device includes: an array of FET-based sensors, wherein the sensors are grouped into multiple channels, and wherein each of the sensors includes an insulator on a substrate, a local gate embedded in the insulator, a channel material over the local embedded gate, and source and drain electrodes in contact with opposite ends of the channel material, and wherein a surface of the channel material is functionalized to react with at least one target molecule. The sensors in a given channel can be modulated (via the local gate) to enable the signal read out from the channel to be divided in the frequency domain based on the different frequencies used to modulate the sensors.
