A robust method to calculate the volume phase transition temperature (VPTT) for hydrogels and hybrids
Bandyopadhyay, Sulalit; Sharma, Anuvansh; Alvi, Muhammad Awais Ashfaq; Raju, Rajesh; Glomm, Wilhelm (Journal article; Peer reviewed, 2017)Here, we report three different methods to determine the volume phase transition temperature (VPTT) of various systems including poly(N-isopropylacrylamide) (pNIPAm) based nanogels, Au nanoclusters and a combination of ... -
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 ... -
Generally applicable procedure for in situ formation of fluorescent protein-gold nanoconstructs
Volden, Sondre; Lystvet, Sina Maria; Halskau jr, Øyvind; Glomm, Wilhelm (Journal article; Peer reviewed, 2012)Small noble metal nanoclusters can be formed in situ by direct reduction and stabilization of a metal precursor by biomolecules such as proteins. Considering the diversity in amino acid composition of proteins, and hence ... -
HAMLET forms annular oligomers when deposited with phoshpolipid monolayers
Baumann, Anne; Gjerde, Anja Underhaug; Ying, Ming; Svanborg, Catharina; Holmsen, Holm A; Glomm, Wilhelm; Martinez, Aurora; Halskau jr, Øyvind (Journal article; Peer reviewed, 2012)Recently, the anticancer activity of human α-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive ... -
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 ... -
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 ... -
