Abstract: Provided herein are methods for imaging subwavelength structures in three dimensions and with high resolution. The methods comprise illuminating subwavelength structures with an illuminating wavelength of light and detecting the self-image generated thereby at a distance distal to the structures. Also provided is a method for confining propagating light to a sub-diffraction limit dimension by illuminating a surface of a metal structure with subwavelength features with a wavelength of coherent light such that light propagating from the features is confined to a dimension that is a sub-diffraction limit thereof.

Abstract: The present invention generally relates to high density nucleic acid arrays and methods of synthesizing nucleic acid sequences on a solid surface. Specifically, the present invention contemplates the use of stabilized nucleic acid primer sequences immobilized on solid surfaces, and circular nucleic acid sequence templates combined with the use of isothermal rolling circle amplification to thereby increase nucleic acid sequence concentrations in a sample or on an array of nucleic acid sequences.

Abstract: The coating of silicon surfaces is described, including but not limited to coating silicon surfaces with biomolecules such as biotin and avidin. Silicon surfaces are made with a monolayer of the protein streptavidin and these surfaces are then used as supports for reactions, including but not limited to nucleic acid hybridization.

Abstract: Disclosed is a method and apparatus for gel electrophoresis which simultaneously employs two or more electric fields in a single gel. According to this invention, which is defined as Multiple-Zone Pulsed-Field Gel Electrophoresis (MZPFGE), the electric field is set to different values in two or more spatially distinct regions of the gel. The difference in values may be related to time dependence, field amplitude or both.
