Abstract: The objects of the present invention are to provide a new technology platform for quantitation number of copies of nucleic acid molecules of interest by lumonogenic (i.e., enzymatic luminescence) detection. The detection approach of the method of present invention is essentially employing time-resolved approach, e.g., based on detection transient parameters of luminescent signal. The various disclosed embodiments allow DNA and RNA quantification in a broad dynamic range; can be used for detection of DNA, as well as long (mRNA) and short (microRNA) RNA targets. The present invention provides methods, instruments, and kits for fast and highly sensitive identification and measurements of nucleic acids in various life science and biomedical applications.

Abstract: The present invention relates to assays for measurement activity of enzymes acting to produce products by consuming ATP or dATP substrate. The assays can also be used to identify and screen for substances that modulate the activity of ATP- and dATP-dependent enzymes.

Abstract: A method and kit are provided for visualization of a latent pattern of molecular structures on a substrate surface. The method is comprised of exposing the substrate to a solution of nano-particles or to a powder of nano-particles. A detectable change is brought about as a result of non-specific binding nano-particles to the chemical groups on the substrate surface carrying the target molecular structures. The invention also provides compositions and kit for practicing the method. Further, the invention provides methods of capturing image of the substrate surface for visualization and quantitation of the molecular structures.

Abstract: A method and apparatus are provided for identifying molecular structures within a sample substance using an integrated circuit array sensor having a plurality of test sites upon which the sample substance is applied. Each test site includes a probe formed therein to bond with an associated target molecular structure. An electrical signal produced on the test site upon forming or breaking of molecular probe-target duplexes is detected to determine which probes have bonded to an associated target molecular structure.

Abstract: Devices and techniques are disclosed for sequencing, fingerprinting, or mapping bio-polymer molecules in micro-array format by tagging molecules with radiation absorbing particles and exposing tagged molecules to electromagnetic radiation such as microwave radiation. The use of radiation absorbing material for tagging enhances detection sensitivity by dissipating energy of the radiation in spots on surface where tagged molecules are located. Proposed system can be particularly beneficial when used as a reader system for DNA and protein microarrays in genomic and proteomic applications, for reading affinity assays, and for detection of a trace amount of chemical or biological species of interest on a surface.
