(Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)Nanoparticulate systems with an uncharged hydrophilic surface may have a great potential in mucosal drug delivery. In the present study liposomes were coated with hydrophobically modified hydroxyethyl cellulose (HM-HEC) ...
-
(Master thesis / Masteroppgave, 2018)There is a need for comprehensive analysis of the dried blood spot (DBS) metabolome to study both new and known inborn errors of metabolism (IEM). The purpose of this study was to complete and evaluate an untargeted ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)Neurons communicate via chemical signals called neurotransmitters (NTs). The numerous identified NTs can have very different physiochemical properties (solubility, charge, size etc.), so quantification of the various NT ...
