    • Controlling the self-assembly and optical properties of gold nanoclusters and gold nanoparticles biomineralized with bovine serum albumin 

      McDonagh, Birgitte Hjelmeland; Singh, Gurvinder; Bandyopadhyay, Sulalit; Lystvet, Sina Maria; Ryan, Joseph Anthony; Volden, Sondre; Kim, Eugene; Sandvig, Ioanna; Sandvig, Axel; Glomm, Wilhelm (Journal article; Peer reviewed, 2015)
      While the size-dependent optical properties of BSA-stabilized gold nanoclusters are well known, the time-dependent growth mechanism remains to be described. Herein, we systematically compare two synthesis methods with and ...

    • Growing gold nanostructures for shape-selective cellular uptake 

      Bandyopadhyay, Sulalit; McDonagh, Birgitte Hjelmeland; Singh, Gurvinder; Raghunathan, Karthik; Sandvig, Axel; Sandvig, Ioanna; Andreassen, Jens-Petter; Glomm, Wilhelm (Journal article; Peer reviewed, 2018)
      With development in the synthesis of shape- and size-dependent gold (Au) nanostructures (NSs) and their applications in nanomedicine, one of the biggest challenges is to understand the interaction of these shapes with ...

    • Incorporation of Fe@Au nanoparticles into multiresponsive pNIPAM-AAc colloidal gels modulates drug uptake and release 

      Bandyopadhyay, Sulalit; Andersen, Marte Kee; Awais, Muhammad; Sharma, Anuvansh; Raju, Rajesh; McDonagh, Birgitte Hjelmeland; Glomm, Wilhelm (Journal article; Peer reviewed, 2016)
      Here, a synthetic method has been optimized for the synthesis of thermoresponsive and pH-responsive poly(N-isopropylacrylamide-co-acrylic acid) nanogels which are subsequently loaded with cytochrome C by using a modified ...

    • L-DOPA-Coated Manganese Oxide Nanoparticles as Dual MRI Contrast Agents and Drug-Delivery Vehicles 

      McDonagh, Birgitte Hjelmeland; Singh, Gurvinder; Hak, Sjoerd; Bandyopadhyay, Sulalit; Augestad, Ingrid Lovise; Peddis, Davide; Sandvig, Ioanna; Sandvig, Axel; Glomm, Wilhelm (Journal article; Peer reviewed, 2016)
      Manganese oxide nanoparticles (MONPs) are capable of time-dependent magnetic resonance imaging contrast switching as well as releasing a surface-bound drug. MONPs give T2/T2* contrast, but dissolve and release T1-active ...

    • Multifunctional Nanoparticles for Bioimaging 

      McDonagh, Birgitte Hjelmeland (Doctoral thesis at NTNU;2015:320, Doctoral thesis, 2015)
      Bioimaging is a broad term that covers all processes in which biological tissues are imaged. It can range from single-cell visualization with fluorescence microscopy, to imaging of brain structures in living human beings ...

    • Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery 

      Mørch, Ýrr Asbjørg; Hansen, Rune; Berg, Sigrid; Åslund, Andreas; Glomm, Wilhelm; Eggen, Siv; Schmid, Ruth; Johnsen, Heidi; Kubowicz, Stephan; Snipstad, Sofie; Sulheim, Einar; Hak, Sjoerd; Singh, Gurvinder; McDonagh, Birgitte Hjelmeland; Blom, Hans; Davies, Ruth Catharina de Lange; Stenstad, Per Martin (Journal article, 2015)
      Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology ...

    • Optimalised Carbodiimide Chemistry for RGD-coupled Alginate 

      McDonagh, Birgitte Hjelmeland (Master thesis, 2012)
      Alginate is a naturally ocurring polyanion of (1→4)linked β-d-mannuronic acid (M)and its C-5 epimer α-l guluronic acid (G). The polyanion, and particularly longstretches of guluronic acids, chelates and form hydrogels in ...

    • Programmable Biopolymers for theranostic applications. 

      Din, Haris Ud (Master thesis, 2016)
      Biopolymers hold great potential in drug delivery and tissue engineering applications. Alginates, a natural polysaccharide derived from brown algae, possess unique properties in terms of gel formation and their interaction ...
