  1. 26. The Effect of Protein Corona on Gold Nanoparticles Aggregation

    University essay from Lunds universitet/Kemiska institutionen

    Author : Nada Abdulla; [2015]
    Keywords : cow serum and IgG; PGB1; corona; Gold nanoparticles; Protein Science; proteinvetenskap; Chemistry;

    Abstract : Nanoparticles (NPs) are the particles between 1 and 100 nm. They are widely used in the medical field as delivery vehicles, therapeutics and contrast agents in cancer diagnosis and treatment. There are different types of NPs divided according to the source of used materials. READ MORE

  3. 27. Fabrication of surface enhanced Raman spectroscopy (SERS) active substrates based on vertically aligned nitrogen doped carbon nanotube forest

    University essay from Umeå universitet/Institutionen för fysik

    Author : Md Khorshed Alam; [2015]
    Keywords : Photolithography; Physical Vapor Deposition; Chemical Vapor Deposition; Annealing; Scanning Electron Microscopy; Surface Enhanced Raman Spectroscopy;

    Abstract : This thesis work describes the fabrication and surface enhanced Raman spectroscopy (SERS) characterization of vertically aligned nitrogen (N) doped multi walled carbon nanotube (MWCNT) forests coated by silver (Ag) and gold (Au) nanoparticles. In the present work, the CNT forests were grown from a catalyst metal layer by the chemical vapor deposition (CVD) process at temperature of 800 oC and a physical vapor deposition (PVD) and annealing processes were applied subsequently for the evaporation and diffusion of noble metal nanoparticles on the forest.
