  1. 1. Multimodal applications in medical technology that utilize Raman spectroscopy

    Författare :Joel Wahl; Kerstin Ramser; Mikael Sjödahl; Thomas Bocklitz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Raman spectroscopy; Preprocessing; Pulmonary arterial smooth muscle cells; Brain tumors; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Biology can often be explained by structures and interactions between molecules. It is therefore of importance for medical sciences that the chemical reactions and molecular compositions of biological samples can be measured. The purpose of this thesis is twofold. LÄS MER

  3. 2. Application of Raman and Fluorescence Spectroscopy to Single Chromatographic Beads

    Författare :Mina Larsson; Jan Lindgren; Jean-Claude Lassègues; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; agarose; chelating group; confocal Raman spectroscopy; confocal scanning laser microscopy; gold nanoparticles; ligand distribution; functional group; neodymium; polymer beads; Raman; SERS; surface-enhanced Raman spectroscopy; Kemi; Chemistry; Kemi;

    Sammanfattning : Chromatography is a powerful technique, essential in chemical analyses and preparative separation in industry and research. Many different kinds of chromatographic material are needed, due to the large variety of applications. Detailed methods of characterisation are needed to design new chromatographic materials and understand their properties. LÄS MER

  4. 3. Quantitative Surface Enhanced Raman Spectroscopy

    Författare :Anders Lorén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gold colloids; internal standard; surface enhanced Raman spectroscopy; SERS; PLS; PCA; SAM; quantitative;

    Sammanfattning : Surface enhanced Raman spectroscopy (SERS) is a very attractive technique for detection of various organic and inorganic molecules due to its sensitivity and selectivity. The surface enhancement is achieved when the molecules of interest are on or in the vicinity of a metal surface, usually gold and silver. LÄS MER
