Patent number: 10203307Abstract: Systems, methods, and apparatus provide integration of microscopic imaging and liquid chromatography-mass spectrometry on a microfluidic device. In one aspect, an apparatus includes a first wafer, a second wafer, and an emitter. The emitter is disposed between the first wafer and the second wafer. The first wafer defines a sample input hole. The first wafer and the second wafer define a first channel, the first channel including a first end and a second end. The first end of the first channel is proximate the sample input hole. The first channel is configured to contain separation media. The second end of the first channel is proximate the emitter.Type: GrantFiled: June 3, 2015Date of Patent: February 12, 2019Assignee: The Regents of the University of CaliforniaInventors: Daojing Wang, Pan Mao, Rafael Gomez-Sjoberg, Hung-Ta Wang, Peidong Yang

Patent number: 9793477Abstract: The present invention provides for a structure comprising a plurality of emitters, wherein a first nozzle of a first emitter and a second nozzle of a second emitter emit in two directions that are not or essentially not in the same direction; wherein the walls of the nozzles and the emitters form a monolithic whole. The present invention also provides for a structure comprising an emitter with a sharpened end from which the emitter emits; wherein the emitters forms a monolithic whole. The present invention also provides for a fully integrated separation of proteins and small molecules on a silicon chip before the electrospray mass spectrometry analysis.Type: GrantFiled: December 20, 2013Date of Patent: October 17, 2017Assignee: The Regents of The University of CaliforniaInventors: Daojing Wang, Pan Mao, Hung-Ta Wang, Peidong Yang

Patent number: 9316637Abstract: Embodiments of the invention include sensors comprising high electron mobility transistors (HEMTs) with capture reagents on a gate region of the HEMTs. Example sensors include HEMTs with a thin gold layer on the gate region and bound antibodies; a thin gold layer on the gate region and chelating agents; a non-native gate dielectric on the gate region; and nanorods of a non-native dielectric with an immobilized enzyme on the gate region. Embodiments including antibodies or enzymes can have the antibodies or enzymes bound to the Au-gate via a binding group. Other embodiments of the invention are methods of using the sensors for detecting breast cancer, prostate cancer, kidney injury, glucose, metals or pH where a signal is generated by the HEMT when a solution is contacted with the sensor. The solution can be blood, saliva, urine, breath condensate, or any solution suspected of containing any specific analyte for the sensor.Type: GrantFiled: December 6, 2013Date of Patent: April 19, 2016Assignee: University of Florida Research Foundation, Inc.Inventors: Fan Ren, Stephen John Pearton, Tanmay Lele, Hung-Ta Wang, Byoung-Sam Kang

Patent number: 8835984Abstract: Embodiments of the invention include sensors comprising AlGaAs/GaAs high electron mobility transistors (HEMTs), inGaP/GaAs HEMTs. InAlAs/InGaAs HEMTs, AlGaAs/InGaAs PHEMTs, InAlAs/InGaAs PHEMTs, Sb based HEMTs, or InAs based HEMTs, the HEMTs having functionalization at a gate surface with target receptors. The target receptors allow sensitivity to targets (or substrates) for detecting breast cancer, prostate cancer, kidney injury, chloride, glucose, metals or pEI where a signal is generated by the HEMI when a solution is contacted with the sensor. The solution can be blood, saliva, urine, breath condensate, or any solution suspected of containing any specific analyte for the sensor.Type: GrantFiled: March 20, 2009Date of Patent: September 16, 2014Assignee: University of Florida Research Foundation, Inc.Inventors: Fan Ren, Stephen John Pearton, Tanmay Lele, Hung-Ta Wang, Byoung-Sam Kang
