Patent number: 6870627Abstract: Disclosed is apparatus and method for controlled surface plasmon resonance analysis having a surface plasmon resonance sensor (200) with a derivatized surface plasmon layer (116) in optical communication with the sensor, derivatizing the surface plasmon layer and placing an analyte detection chamber (102) in fluid communication with the derivatized surface plasmon layer. The chamber is adapted (118, 120) for the generation of a molecular interaction bias across the chamber. A conjugate is provided between an analyte and a bias responsive element, wherein the analyte is reactive with the derivatized surface plasmon layer and the bias responsive element changes the response of the analyte to the molecular interaction bias. A conjugated analyte may be introduced into the chamber, generating a molecular interaction.Type: GrantFiled: October 27, 2003Date of Patent: March 22, 2005Assignee: Texas Instruments IncorporatedInventors: Jerome L.

Patent number: 6798521Abstract: A surface plasmon resonance (SPR) sensor (10) is disclosed. The sensor (10) includes a light source (18) and polarizer (20), which emit polarized light toward a surface plasmon layer (22). Light is reflected from the surface plasmon layer (22) at many angles, toward a photodetector array (26) via a mirror surface (24). The surface plasmon layer (22) includes a resonance film (30), such as gold, and a hard protective layer (32). The hard protective layer (32) is of a thickness below the sensing range (R) of the SPR sensor (10), and protects the resonance film (30) from damage. Materials useful as the hard protective layer (32) include silicon carbide (SiC), diamond-like carbon (DLC), silicon dioxide, silicon nitride, titanium oxide, titanium nitride, aluminum oxide, aluminum nitride, beryllium oxide, and tantalum oxide.Type: GrantFiled: October 25, 2001Date of Patent: September 28, 2004Assignee: Texas Instruments IncorporatedInventors: Jerome L.

Publication number: 20030059342Abstract: An agitated flow cell had a micro/miniature vibrator device such as pager motor to agitate the flow cell and its associated sensor to bring fresh analyte to the sensor surface without the need for microfluidic channels, pumps or valves. The agitated flow cell improves the confidence measure of a given sample reading by directing the flow of sample to the sensor/sample interface in a substantially shorter period of time than that required by flow cells that rely on diffusion of analyte molecules through the liquid depletion region in order to bring the sample reliably in contact with the sensor's biosensing film.Type: ApplicationFiled: September 26, 2001Publication date: March 27, 2003Inventor: Jerome L.

Patent number: 5318666Abstract: A method of forming an n-p junction in a body (44, 44a, 44b) formed of Group II and Group VI elements. The body (44, 44a, 44b) initially is of p-type conductivity characteristic, and a dry reactive etching process is employed for forming a via (60, 60a, 60b) in the body by a chemical reaction which is also effective to type convert a portion of the body adjacent the via. An n-doped region (64, 64a, 64b) is thereby formed within the body around the via and between the via and the remaining, p-doped region of the body, thereby defining an n-p junction. In one embodiment, the body is mounted on an electrical device (50, 50a, 50b) having an input contact pad (58, 58a, 58b), and an electrically conductive layer (62, 46a, 90) is formed in connection with the contact pad and the n-doped region adjacent the via.Type: GrantFiled: April 19, 1993Date of Patent: June 7, 1994Assignee: Texas Instruments IncorporatedInventors: Jerome L. Elkind, Glennis J. Orloff, Patricia B. Smith

Patent number: 5157000Abstract: A process is disclosed through which vias (50) can be formed by the reaction of an etchant species (52) with a mercury cadmium telluride (HgCdTe) or zinc sulfide (ZnS) layer (42). The activating gases (20) are preferably a hydrogen gas or a methane gas which is excited in a diode plasma reactor (100) which has an RF power source (13) applied to one of two parallel electrodes. The etching occurs in selected areas in a photoresist pattern (44) residing over the ZnS or HgCdTe layer (42). Wet etching the layer (42) with a wet etchant (54) following the dry etching, improves the via (50) by making the walls (48) smoother, and allowing for expansion of the vias (50) to a dimension necessary for proper operation of a HgCdTe-based infrared detector.Type: GrantFiled: February 8, 1991Date of Patent: October 20, 1992Assignee: Texas Instruments IncorporatedInventors: Jerome L.
