A Single Electron MOS Memory (SEMM), in which one bit of information is represented by storing only one electron, has been demonstrated at room temperature. The SEMM is a floating gate Metal-Oxide-Semiconductor (MOS) transistor in silicon with a channel width (about 10 nanometers) which is smaller than the Debye screening length of a single electron stored on the floating gate, and a nanoscale polysilicon dot (about 7 nanometers by 7 nanometers by 2 nanometers) as the floating gate which is positioned between the channel and the control gate. An electron stored on the floating gate can screen the entire channel from the potential on the control gate, and lead to: (i) a discrete shift in the threshold voltage; (ii) a staircase relation between the charging voltage and the shift; and (iii) a self-limiting charging process. The structure and fabrication of the SEMM is well adapted to the manufacture of ultra large-scale integrated circuits.

An electrical detector is provided that comprises a nanofluidic channel with an integrated nanoscale charge sensor. The charge sensor can be an unfunctionalized nanowire, nanotube, transistor or capacitor and can be of carbon, silicon, carbon / silicon or other semiconducting material. The nanofluidic channel depth is on the order of the Debye screening length. Methods are also provided for detecting charged molecules or biological or chemical species with the electrical detector. Charged molecules or species in solution are driven through the nanofluidic channel of the electrical detector and contact the charge sensor, thereby producing a detectable signal. Methods are also provided for detecting a local solution potential of interest. A solution flowing through the nanofluidic channel of the electrical detector contacts the charge sensor, thereby producing a detectable local solution potential signal.

A plasma processing system includes a source of plasma, a substrate and a shutter positioned in close proximity to the substrate. The substrate / shutter relative disposition is changed for precise control of substrate / plasma interaction. This way, the substrate interacts only with a fully established, stable plasma for short times required for nanoscale processing of materials. The shutter includes an opening of a predetermined width, and preferably is patterned to form an array of slits with dimensions that are smaller than the Debye screening length. This enables control of the substrate / plasma interaction time while avoiding the ion bombardment of the substrate in an undesirable fashion. The relative disposition between the shutter and the substrate can be made either by moving the shutter or by moving the substrate.

According to one aspect, the disclosure is directed to an example embodiment in which a circuit-based arrangement includes a circuit-based substrate securing a channel, with an effective width that is not limited by the Debye screening length, along a surface of the substrate. A pair of reservoirs are included in or on the substrate and configured for containing and presenting a sample having bio-molecules for delivery in the channel. A pair of electrodes electrically couple a charge in the sample to enhance ionic current flow therein (e.g., to overcome the electrolyte screening), and a sense electrode is located along the channel for sensing a characteristic of the biological sample by using the electrostatic interaction between the enhanced ionic current flow of the sample and the sense electrode. Actual detection occurs by using a charge-signal processing circuit to process the sensed charge signal and, therefrom, provide an output indicative of a signature for the bio-molecules delivered in the channel.

Techniques and instrumentation are described for analyses of substances, including complex samples / mixtures that require separation prior to characterization of individual components. A method is disclosed for separation of ion mixtures and identification of ions, including protein and other macromolecular ions and their different structural isomers. Analyte ions are not free to rotate during the separation, but are substantially oriented with respect to the drift direction. Alignment is achieved by applying, at a particular angle to the drift field, a much stronger alternating electric field that “locks” the ion dipoles with moments exceeding a certain value. That value depends on the buffer gas composition, pressure, and temperature, but may be as low as ˜3 Debye under certain conditions. The presently disclosed method measures the direction-specific cross-sections that provide the structural information complementing that obtained from known methods, and, when coupled to those methods, increases the total peak capacity and specificity of gas-phase separations. Simultaneous 2-D separations by direction-specific cross sections along and orthogonally to the ion dipole direction are also possible.

The present invention discloses a method to improve the image resolution of a microscope. This improvement is based on the mathematical processing of the complex field computed from the measurements with a microscope of the wave emitted or scattered by the specimen. This wave is, in a preferred embodiment, electromagnetic or optical for an optical microscope, but can be also of different kind like acoustical or matter waves. The disclosed invention makes use of the quantitative phase microscopy techniques known in the sate of the art or to be invented. In a preferred embodiment, the complex field provided by Digital Holographic Microscopy (DHM), but any kind of microscopy derived from quantitative phase microscopy: modified DIC, Shack-Hartmann wavefront analyzer or any analyzer derived from a similar principle, such as multi-level lateral shearing interferometers or common-path interferometers, or devices that convert stacks of intensity images (transport if intensity techniques: TIT) into quantitative phase image can be used, provided that they deliver a comprehensive measure of the complex scattered wavefield. The hereby-disclosed method delivers superresolution microscopic images of the specimen, i.e. images with a resolution beyond the Rayleigh limit of the microscope. It is shown that the limit of resolution with coherent illumination can be improved by a factor of 6 at least. It is taught that the gain in resolution arises from the mathematical digital processing of the phase as well as of the amplitude of the complex field scattered by the observed specimen. In a first embodiment, the invention teaches how the experimental observation of systematically occurring phase singularities in phase imaging of sub-Rayleigh distanced objects can be exploited to relate the locus of the phase singularities to the sub-Rayleigh distance of point sources, not resolved in usual diffraction limited microscopy. In a second, preferred embodiment, the disclosed method teaches how the image resolution is improved by complex deconvolution. Accessing the object's scattered complex field—containing the information coded in the phase—and deconvolving it with the reconstructed complex transfer function (CTF) is at the basis of the disclosed method. In a third, preferred embodiment, it is taught how the concept of “Synthetic Coherent Transfer Function” (SCTF), based on Debye scalar or Vector model includes experimental parameters of MO and how the experimental Amplitude Point Spread Functions (APSF) are used for the SCTF determination. It is also taught how to derive APSF from the measurement of the complex field scattered by a nanohole in a metallic film. In a fourth embodiment, the invention teaches how the limit of resolution can be extended to a limit of λ / 6 or smaller based angular scanning. In a fifth embodiment, the invention teaches how the presented method can generalized to a tomographic approach that ultimately results in super-resolved 3D refractive index reconstruction.
