The present disclosure relates to devices and methods for the detection and/or sorting of nucleic acids. Further disclosed are methods for device fabrication.

Branched nanochannel devices for detection and sorting of nucleic acids

Methods and systems for producing a three-dimensional structure using electrochemical additive manufacturing are described herein. The methods can comprise injecting a growth control solution into an electrolyte comprising a metal salt to form a growth control region and applying an electric potential to a working electrode to thereby form a layer of metal at a location defined by the growth control region. The injecting and applying steps of the methods can be repeated for form the three-dimensional structure on a layer-by-layer basis.

Methods and systems for electrochemical additive manufacturing

Methods for electrodeposition using aqueous electrolytes where water molecules are depleted are described herein. Methods of electrodepositing superconducting thin films from aqueous electrolytes where water molecules are depleted are also described herein.

Methods for electrodeposition

A waveguide hologram illumination system is based on thin substrate waveguides bearing a hologram on the surface through which light is diffracted out. A light source is optically coupled to the waveguide such that light emitted from the source is caused to propagate along the waveguide, being diffracted out at intersections with the surface of the waveguide on which the hologram is formed. The selective emission through the hologram can be advantageously used to illuminate display holograms or spatial light modulators. Provisions are made for rendering the amount of light emitted through the hologram uniform along the length of the hologram.

Waveguide hologram illuminators

A multimode waveguide having a small thickness has light coupled to the side of the waveguide in order to provide a multimode operation of the waveguide for providing a continuous pattern of totally internally reflected light which is utilized to reconstruct holographic images from a holographic emulsion placed on a surface of the waveguide. This waveguide structure for reconstructuring a hologram has the capability of providing highly efficient hologram reconstruction while using ordinary light sources and is able to use beam diameters greater than the thickness of the waveguide.

Multimode waveguide holograms capable of using non-coherent light

A holographic display and method for displaying hologram are disclosed. The method and apparatus provides a compact display arrangement in which the light source for illuminating the display is integral with the display, or in other words, an external light source is not necessary. The hologram utilized in the display is formed as a rainbow hologram, with a converging reference beam utilized in forming the diffraction grating upon the holographic plate. The display includes a pair of spaced transparent glass sheets, with the light source disposed between the glass sheets. The holographic plate formed with the converging reference beam is then mounted upon one of the glass sheets, with the light source illuminating the holographic plate with diverging illumination light. A mirror is associated with each of the transparent glass sheets at a location adjacent to the light source, with the reflective surfaces of the mirrors facing each other. Thus, the light from the light source is reflected by the mirrors and the transparent sheets, and impinges upon the holographic plate to provide the diverging illumination light. The method and apparatus provides a compact integrated holographic display.
