Publication number: 20190331673Abstract: A method of functionalization of a gate electrode of a field-effect transistor sensor includes forming a layer of biological recognition elements on a surface of said gate electrode, wherein said layer of biological recognition elements includes a self-assembled structure of one or more specific-binding-pair-forming substances (anti-hIg, anti-IgG, anti-IgM). The layer of biological recognition elements is treated with a solution containing a blocking agent to fill vacancies and prevent nonspecific binding in the self-assembled structure. One or more specific-binding-pair-forming substances immobilized in said layer of biological recognition elements are packed at a density of 0.1×104 ?m?2 and 10×104 ?m?2, preferably between 1×104 ?m?2 and 2×104 ?m?2.Type: ApplicationFiled: December 18, 2017Publication date: October 31, 2019Applicant: UNIVERSITA' DEGLI STUDI DI BARI ALDO MOROInventors: Luisa TORSI, Gerardo PALAZZO, Gaetano SCAMARCIO

Patent number: 8234081Abstract: A system measures the strain of an object. The system includes a laser source for generating an output radiation, a strainable optical fiber having first and second facets, and means for calculating a measure of a strain of the optical fiber. The first facet is coupled to the laser source to receive the output radiation and transmit a guided radiation over the optical fiber towards the second facet. The second facet is adapted to receive the guided radiation and to reflect a corresponding reflected radiation towards the first facet. The laser source is a self-mixing type adapted to receive at least part of the reflected radiation and to mix the output radiation with the received radiation. The calculating means calculate the measure of the strain of the optical fiber based on a self-mixing effect in the laser source that is caused by the linear displacement of the second section.Type: GrantFiled: September 21, 2009Date of Patent: July 31, 2012Assignee: Universita degli Studi di BariInventors: Maurizio Dabbicco, Gaetano Scamarcio, Simona Ottonelli, Angela Intermite, Branimir Radisavljevic

Patent number: 6690699Abstract: An optical gain medium has first and second active layers and an injector layer interposed between the first and second active layers. The active layers have upper minibands and lower minibands. The injector layer has a miniband that transports charge carriers from the lower miniband of the first active layer to an excited state in the upper miniband of the second active layer in response to application of a voltage across the optical gain medium.Type: GrantFiled: February 21, 2002Date of Patent: February 10, 2004Inventors: Federico Capasso, Alfred Yi Cho, Albert Lee Hutchinson, Gaetano Scamarcio, Deborah Lee Sivco, Mariano Troccoli

Patent number: 5936989Abstract: The core of the disclosed novel quantum cascade (QC) laser comprises a multiplicity of nominally identical repeat units, with a given repeat unit comprising a superlattice active region and a carrier injector region. Associated with the superlattice active region is an upper and a lower energy miniband, with the lasing transition being the transition from the lower edge of the upper miniband to the upper edge of the lower miniband. The injector facilitates carrier transport from the lower miniband to the upper miniband of the adjacent downstream repeat unit. QC lasers according to this invention can be designed to emit in the infrared, e.g., in the wavelength region 3-15 .mu.m, and can have high power.Type: GrantFiled: April 29, 1997Date of Patent: August 10, 1999Assignee: Lucent Technologies, Inc.Inventors: Federico Capasso, Alfred Yi Cho, Jerome Faist, Albert Lee Hutchinson, Gaetano Scamarcio, Carlo Sirtori, Deborah Lee Sivco

Patent number: 5745516Abstract: The novel unipolar laser resembles a quantum cascade laser but utilizes radiative transitions between upper and lower minibands of superlattices, with injection of charge carriers from the lower miniband into the upper miniband of the adjacent downstream superlattice facilitated by a multilayer injector region. The lasing wavelength is typically in the mid-infrared, selectable by choice of the superlattice parameters. The novel laser is potentially well suited for high power operation, since it utilizes carrier transport in minibands, as opposed to tunneling between discrete energy states.Type: GrantFiled: November 6, 1996Date of Patent: April 28, 1998Assignee: Lucent Technologies Inc.Inventors: Federico Capasso, Alfred Yi Cho, Jerome Faist, Albert Lee Hutchinson, Gaetano Scamarcio, Carlo Sirtori, Deborah Lee Sivco
