Abstract: What has been developed is an improved method of determining the binding constants between two molecules that requires significantly fewer materials and potentially less time (in the case of a whole cell analysis less time to grow cell cultures as fewer cells are required in the same analysis) to undertake. The method involves utilizing an NSB measurement in preferably an n-curve analysis in order to determine the Kd and/or Rt without having to complete actual measurements to determine the lower knee of the curve(s) in the n-curve analysis. Preparing the experiment utilizing the additional samples allows an experiment represented in a binding curve having an upper and a lower knee to no longer be required to run through the lower knee to a point of completion.

Abstract: The present disclosure is directed toward improved methods of conducting a competitive binding assay or experiment. The methodology includes utilizing either a positive control, a negative control, or both in order to scale experimentation results to results that can be utilized to obtain a precise measurement of the kinetic rate constant (the off rate denoted as koff) describing the dissociation of a non-covalent complex such as an antibody antigen complex, receptor ligand complex, etc.

Abstract: A method for fabricating an integrated circuit using a photo-lithographic process includes the steps of placing at least two anti-reflective coating layers between a reflective surface and another material. The indices of refraction, absorptions, and thicknesses of the at least two anti-reflective coating layers are chosen such that the amplitudes and phase differences of radiation reflected from the anti-reflective coating layers, as well as any other reflective surfaces below the anti-reflective coating layers, mutually cancel when combined. The invention may be practiced using more than two layers of anti-reflective coating. Multiple layers of anti-reflective coating may be used below an inter-level dielectric, in which case they may serve the additional purpose of functioning as an etch-stop.

The fuse also includes an absorption element comprising a material with an adjustable capacity for heat or light absorption that overlays the heat conductive element. The fuse also includes an outer insulating element that overlays and encloses the heat conductive element and the absorption element.

Abstract: The present invention comprises construction of a display from display elements that are actuated using the physical principle of electrowetting. In one embodiment, pores within porous silicon are filled with an ionic and an optically reflective electronic conductor, and actuated by application of an electric potential across the pore. An image is then formed on an array of such pores by applying an appropriate voltage to each pore of the array to create an optical image in the light reflected off the electronic conductors. Such a display may be constructed to have very high resolution, making it desirable for creating real-time holographic images, or for creating high-resolution mask images for use in photolithography.

Abstract: The present invention provides an improved system for detecting the presence or level of an analyte in a sample. In “competition-like” assays of the present invention, a sample including an analyte is mixed with a second ligand to which the analyte binds, and the mixture is exposed to a solid phase containing a first ligand that can compete with the analyte for binding to the second ligand. According to the present invention, the time of exposure of the mixture to the solid phase is limited so that substantially no dissociation of analyte/second ligand complex occurs. The competition-like assays of the present invention are preferably performed with a solid phase containing a substantial excess of first ligand. In “sandwich-type” assays of the present invention, a sample including an analyte is contacted with a solid phase including a first ligand that binds the analyte and, simultaneously or subsequently, is contacted with a second ligand that binds the analyte (or the analyte/first ligand complex).
