    Abstract : Bioanalytical applications using supercritical fluid chromatography (SFC) as analytical technique are of increasing interest. In essence, bioanalysis involves measurement of bioactive or endogenous compounds in biological matrices. READ MORE

  6. 24. Advances for Biomarker Discovery in Neuroproteomics using Mass Spectrometry : From Method Development to Clinical Application

    Author : Marcus O.D. Sjödin; Magnus Wetterhall; Jonas Bergquist; Dominic M. Desiderio; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mass Spectrometry; Biomarker; Proteomics; Central Nervous System; Cerebrospinal Fluid; Traumatic Brain Injury; Cloud-Point Extraction; Neuroproteomics; Relative Quantification; Spinal Cord Stimulation; Neuropathic Pain; Analytical Chemistry; Analytisk kemi;

    Abstract : Proteins offer a prominent group of compounds which may be ubiquitously affected in disease and used as biomarkers for early diagnosis, assessing treatment or drug development. Clinical proteomics aim to screen for protein biomarkers by a comprehensive analysis of all proteins expressed in a biological matrix during a certain pathology. READ MORE

  7. 25. Mass Spectrometry with Electrospray Ionization from an Adjustable Gap

    Author : Patrik Ek; Åsa Emmer; Johan Roeraade; Per M. Claesson; Ulrika Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electrospray ionization; mass spectrometry; nanoelectrospray; ESI; MS; chip; emitter; gap; liquid bridge; nozzle; peptides; Analytical chemistry; Analytisk kemi;

    Abstract : In this thesis the fabrication and analytical evaluation of two new electrospray emitters utilized for mass spectrometry analysis is presented. The emitters are based on a new concept, where the spray orifice can be varied in size. The thesis is based on two papers. All present-day nanoelectrospray emitters have fixed dimensions. READ MORE
