  2. 11. In situ gelling drug delivery systems for periodontal anaesthesia

    Author : Marie Scherlund; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; anestesiologi; Anaesthesiology;

    Abstract : In this thesis local anaesthetic formulations based on PEO-PPO-PEO block copolymers (PEO and PPO being poly(ethylene oxide) and poly(propylene oxide), respectively) or nonionic cellulose ethers undergoing temperature- or dilution-induced thickening were investigated. The aim of the work was to develop formulations which can be easily administered to the periodontal pocket, stay at the application site, give a fast onset of anaesthesia and have a duration sufficient to perform periodontal scaling procedures.

  4. 12. Charged colloids observed by electrophoretic and diffusion NMR

    Author : Erik Thyboll Pettersson; Peter Stilbs; Terence Cosgrove; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; ENMR; electrophoretic NMR; dissusion NMR; electrophoretic mobility; double stimulated echo; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : The thesis deals partly with methodology including construction of hardware and new pulse sequences in the field of electrophoretic NMR, and partly with practical use of ENMR and diffusion NMR in the investigation of charged colloidal systems. Several sources of artefacts are investigated, including gas production at the electrodes, electroosmosis and Joule heating effects that can cause convection. READ MORE

  5. 13. Rational design of nanoparticles for biomedical imaging and photovoltaic applications

    Author : Haiyan Qin; Hans Ågren; Alexander Dmitriev; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

    Abstract : This thesis aims to rationally design nanoparticles and promote their applications in biomedical imaging and photovoltaic cells. Quantum dots (QDs) are promising fluorescent probes for biomedical imaging. READ MORE
