  1. 1. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Freja Hansson; [2021]
    Keywords : Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

    Abstract : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. READ MORE

  3. 2. Development of Next-Generation Optical Tweezers : The New Swiss Army Knife of Biophysical and Biomechanical Research

    University essay from Umeå universitet/Institutionen för fysik
