  2. 1. Microscale Tools for Sample Preparation, Separation and Detection of Neuropeptides

    Author : Andreas Dahlin; Jonas Bergquist; Karin E. Markides; Robert T. Kennedy; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Neuropeptides; Microchip; Enhanced microdialysis; Poly dimethylsiloxane PDMS ; Electrospray ionization ESI ; Multidimensional separation; Electrochemical manipulation; Mass spectrometry MS ; Capillary electrophoresis CE ; Microdevice; Microfabrication; Micro total analysis system μ-TAS ; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : The analysis of low abundant biological molecules is often challenging due to their chemical properties, low concentration and limited sample volumes. Neuropeptides are one group of molecules that fits these criteria. Neuropeptides also play an important role in biological functions, which makes them extra interesting to analyze. READ MORE

  4. 2. Endothelial function during ischemia-reperfusion and effects of inhalation of nitric oxide

    Author : Lars Lindberg; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chemiluminescence; capnography; monitoring; inhalation; mechanical ventilation; pulmonary hypertension; nitric oxide; EDRF; endothelium-derived relaxation factor; endothelium; organ preservation; Lung; lung transplantation; electrochemical fuel cell; Anaesthesiology; intensive care; Anestesiologi; intensivvård;

    Abstract : The vascular endothelium is an important regulatory organ in circulatory physiology and plays a central role in the response to acute inflammation and ischemia/reperfusion. Activation and dysfunction of the pulmonary vascular endothelium are closely related to clinical findings of pulmonary dysfunction. READ MORE

  5. 3. Integration of Surface Acoustic Wave and Microfluidic Technologies for Liquid-Phase Sensing Applications

    Author : Kiryl Kustanovich; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IDE; Resonator; SH-SAW; Impedance Spectroscopy; Surface Acoustic Wave; PDMS; LiNbO3; Microfluidics; Sensor;

    Abstract : This thesis discusses a new concept for construction of a novel SAW in-liquid sensor employing surface acoustic wave resonance (SAR) in a one-port configuration. In this concept, the reflective gratings of a one-port SAW resonator are employed as mass loading-sensing elements, while the SAW transducer is protected from the measurement environment, reducing power losses significantly.
