Abstract: A technique to have precise materials deposition in the micro and nanometer scale relating to 3D printing. A microfluidic pipette and an atomic force microscopy (AFM) needle are used to position the pipette a distance from a working stage to avoid surface tension physics associated with droplet formation of pipette excreted material, “ink.” The combination provides greater control over both the amounts of placement of the ink. In practice, both the AFM needle and the pipette are lowered to a work stage (or the stage is raised to the AFM needle). The pipette excretes a pool of ink onto the stage and the AFM needle is placed into the pool. A unit of ink from the pool adheres to the AFM needle. The AFM needle then moved to a work space on the stage and deposits the ink in the work area through a predetermined printing technique. The system is capable of printing photoresist, polymers, nanomaterials, DNA, proteins, stem cells, semiconductors, metal, plastic and almost anything imaginable.

Abstract: Various embodiments of the present invention contemplates a variety of methods and techniques for fabricating a carbon nanotube (CNT) signal modulator for reducing, eliminating, or enhancing the resonance interaction between photonic elements, and a photonic transmission device that may incorporate the signal modulator. These fabrication techniques can be used to create a nanoantennas, rectennas, and efficient solar energy devices. For example, a photonic collection device can include an array of carbon nanofibers (CNFs), CNTs, nanowires or other suitable conducting material, each having functional antenna forms that are capable of harvesting electromagnetic radiation and directing electrons to a rectifying barrier to generate a DC current. Each CNF in the array can have a diameter and length suitable to allow for the havesting electromagnetic radiation within a range of desired wavelengths.

Abstract: The present invention contemplates a variety of methods and techniques for fabricating a carbon nanotube (CNT) signal modulator for reducing, eliminating, or enhancing the resonance interaction between photonic elements, and a photonic transmission device that may incorporate the signal modulator. The CNT signal modulator comprises a gate CNT on a substrate in a position for receiving an input photonic signal and an input modulation signal; and transmitting an output photonic signal that is reduced, eliminated, or enhanced through the selection of the input modulation signal; and an input modulation signal sender for sending the input modulation signal to the gate CNT and creating the modulated output photonic signal from the gate CNT. The photonic transmission device can contain a plurality of CNTs, each having functional antenna forms that are capable of a resonance interaction of photons between adjacent CNTs when formed as an array on a substrate.

Abstract: An electromagnetic and/or chemical enhancement which greatly enhances the Raman signal response for Surface Enhanced Raman is directed to molecular probe systems. Such molecular probe systems have many properties that make them ideal as probes for Scanning Probe Microscopy, Atomic Force Microscopy, and many other applications.

Abstract: The present invention contemplates a variety of methods and techniques for fabricating an improved carbon nanotube (CNT) device such as an AFM probe. A CNT is first formed on a desired location such as a substrate. The CNT and substrate are then covered with a protective layer through a CVD or other suitable process. Then a length of the CNT is exposed through etching or other suitable process, the exposed length being formed to a length suitable for a desired application for the CNT device.
