Optimization, Cellular Uptake and Cytotoxicity of Lipid Nanoparticles
(Master thesis, 2016)Chemotherapy can potentially be greatly improved by using nanoparticles as drug carriers to deliver chemotherapeutic drugs specifically to cancer cells. Lipid nanoparticles can encapsulate hydrophobic drugs that have low ... -
Optimized differentiation of THP-1 cells into macrophages for the study of TLR4 signaling and trafficking events
(Master thesis, 2014)Toll like receptors (TLRs) are a group of membrane bound pattern recognition receptors (PRRs). TLRs are able to detect a variety of pathogen associated molecular patterns (PAMPs) and start inflammation upon recognition of ... -
Optimized Fast Filtration-based Sampling and Extraction Enables Precise and Absolute Quantification of the Escherichia coli Central Carbon Metabolome
(Peer reviewed; Journal article, 2023)Precise and accurate quantification is a prerequisite for interpretation of targeted metabolomics data, but this task is challenged by the inherent instability of the analytes. The sampling, quenching, extraction, and ... -
Optimized Miniature Two-Photon Microscopy for Imaging Neuronal Activity in Freely Moving Mice
(Master thesis, 2021)Oppfinnelsen av nye avbildningsteknikker har alltid banet vei for påfølgende gjennombrudd i biovitenskapen og det såkalte to-foton mikroskopet er intet unntak. Teknikken muliggjør rask, kalsiumbasert avbildning av ... -
Optimized Nickel-Cobalt and Nickel-Iron Oxide Catalysts for the Hydrogen Evolution Reaction in Alkaline Water Electrolysis
(Journal article; Peer reviewed, 2019)Ni and Ni-doped with transition metals (TM) such as Fe and Co represent the most suitable electrodes for hydrogen evolution reaction (HER) in alkaline media. Various compositions of co-precipitated Ni1 + xFe2 − xO4 and Ni1 ... -
Optimized submerged batch fermentation strategy for systems scale studies of metabolic switching in Streptomyces coelicolor A3(2)
(Journal article; Peer reviewed, 2012)Background: Systems biology approaches to study metabolic switching in Streptomyces coelicolor A3(2) depend on cultivation conditions ensuring high reproducibility and distinct phases of culture growth and secondary ... -
Optimized synthesis of polyacrylic acid-coated magnetic nanoparticles for high-efficiency DNA isolation and size selection
(Peer reviewed; Journal article, 2023)Solid-phase reversible immobilization (SPRI) bead technology is widely used in molecular biology for convenient DNA manipulation. However, commercial SPRI bead kits lack cost advantages and flexibility. It is, therefore, ... -
Optimizing an Infrared Camera for Observing Atmospheric Gravity Waves from a CubeSat Platform
(Master thesis, 2012)The NTNU Test Satellite (NUTS) is a double CubeSat deigned by master students at NTNU. The goal of the project is to image atmospheric gravity waves in the OH airglow layer. This thesis explores the theory behind gravity ... -
