      Vanden-Hehir, Sarah (The University of Edinburgh, 2019-11-28)
      Encapsulating drugs in polymeric nanoparticles (NPs) is becoming increasingly popular for targeted and sustained drug delivery. NP drug delivery systems can increase the lifetime of therapeutics in vivo, they can improve ...
    • Synthesis of s-Tetrazines for biomedical applications 

      Gambardella, Alessia (The University of Edinburgh, 2019-11-28)
      Tetrazines are aromatic six-membered heterocycles, containing four nitrogen atoms that can react as dienes in inverse-electron-demand Diels–Alder (IEDDA) reactions leading to the formation of pyridazines. Owing to their ...
    • Synthesis of optical probes for the visualization of human neutrophil elastase 

      Evans, Vikki (The University of Edinburgh, 2019-11-28)
      Optical medical imaging is a new technology that uses light to improve clinical processes such as disease diagnosis and tumour margin delineation. It has the potential to produce high-resolution images in real-time, with ...

      McNab, Robbie (The University of Edinburgh, 209-11-28)
      In recent years the field of molecular magnetism has focused its attention on creating novel magnetic molecules that can retain their magnetisation in the absence of a magnetic field, below a blocking temperature. These ...
    • Iron and titanium amino-phenolate complexes in controlled alkene polymerisation 

      Coward, Daniel Luke (The University of Edinburgh, 2019-11-28)
      Transition metals have long been used as both catalysts and mediators in the polymerisation of many monomers. This thesis explores the use of iron and titanium amino-phenolate complexes as mediators in the polymerisation ...

      Felemban, Sarah Abdulhalim (The University of Edinburgh, 2019-11-28)
      Polymers of intrinsic microporosity (PIMs) owe their microporosity to their rigid and contorted structure which prevents efficient space packing. Their microporosity and processability make them attractive for many ...
    • Behaviour of intermolecular interactions at extreme pressures 

      Giordano, Nico (The University of Edinburgh, 2019-11-28)
