Publication number: 20190232280Abstract: A sample testing apparatus for characterizing at least one target molecule in a testing sample includes a substrate and at least one detection device over the substrate. Each detection device includes a plurality of electrodes, a plurality of data lines, and a probe. Each electrode is configured, upon reaction of the probe with one of the at least one target molecule, to sense an electrical signal, and then to transmit the electrical signal via the one data line. Each data line includes a first film layer and at least one other film layer disposed over the first film layer. The first film layer can be at a substantially same layer, and have a first composition substantially same, as the electrodes. One or more of the at least one other film layer can have a composition having a relatively lower electric resistance than the first composition.Type: ApplicationFiled: May 17, 2017Publication date: August 1, 2019Applicant: Beijing Boe Optoelectronics Technology Co., Ltd.Inventor: Tiansheng LI

Publication number: 20190232283Abstract: A hand-held molecular diagnostic test device includes a housing, an amplification (or PCR) module, and a detection module. The amplification module is configured to receive an input sample, and defines a reaction volume. The amplification module includes a heater such that the amplification module can perform a polymerase chain reaction (PCR) on the input sample. The detection module is configured to receive an output from the amplification module and a reagent formulated to produce a signal that indicates a presence of a target amplicon within the input sample. The amplification module and the detection module are integrated within the housing.Type: ApplicationFiled: April 5, 2019Publication date: August 1, 2019Applicant: Click Diagnostics, Inc.Inventors: Boris ANDREYEV, Keith E.
