  2. 2. Deposition and absorption of inhaled drugs

    University dissertation from Department of Clinical Physiology, Lund University

    Author : Eva Bondesson; Lund University.; Lunds universitet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; technetium-99m; radionuclide imaging; radioactive aerosol; powder inhaler; pharmacokinetics; mucociliary clearance; lung deposition; gamma scintigraphy; inhalation; deposition modelling; drug absorption; absorption enhancer; aerosol; medicinsk instrumentering; Physiology; Fysiologi;

    Abstract : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.

  3. 3. Modeling colloidal nanoparticles: From growth to deposition

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Joakim Löfgren; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; density functional theory; thermodynamics; nanorods; colloidal nanoparticles; van der Waals; anisotropic; deposition; dispersive interactions; modeling; gold; DLVO;

    Abstract : In recent decades metal nanoparticles (NPs) have been the subject of intense research. The interest stems from the NPs physicochemical properties that can be conveniently tuned through, e.g., their size, shape or composition. READ MORE

  4. 4. Carbon Nanostructures – from Molecules to Functionalised Materials Fullerene-Ferrocene Oligomers, Graphene Modification and Deposition
