Nanomedicine and Sonopermeation in the Treatment of Cancer
(Doctoral theses at NTNU;2019:98, Doctoral thesis, 2018)Treatment of cancer is an enormous challenge that involves multiple biological barriers and drugs with limited specificity, which makes treatment both ineffective and debilitating to the patient. One of the approaches that ... -
Nanomekanisk prøving av stål: Er mindre alltid sterkere?
(Master thesis, 2012)Gjennom dette arbeidet, er nanomekaniske kompresjonsegenskaper undersøkt for tre forskjellige materialer: To stål legeringer og et renjern. Pillarer av varierende størrelse, fra diameter 100nm til 2um, er fabrikkert ved ... -
Nanometer-Resolution Mask Lithography with Matter Waves: Near-Field Binary Holography
(Journal article; Peer reviewed, 2019)Mask-based pattern generation is a crucial step in microchip production. The next-generation extreme-ultraviolet- (EUV) lithography instruments with a wavelength of 13.5 nm are currently under development. In principle, ... -
Nanometer‐Scale Depth‐Resolved Atomic Layer Deposited SiO2 Thin Films Analyzed by Glow Discharge Optical Emission Spectroscopy
(Journal article; Peer reviewed, 2018)In this contribution, pulsed radio frequency (rf) glow discharge optical emission spectroscopy (GDOES) is used to investigate the film properties of SiO2 deposited by plasma enhanced atomic layer deposition (PEALD), for ... -
Nanoparticle additions promote outstanding fracture toughness and fatigue strength in a cast Al–Cu alloy
(Peer reviewed; Journal article, 2020)Fatigue resistance and fracture toughness are essential to the reliability of castings during service. Reducing microporosity in cast alloys is a crucial issue for improving their fatigue strength and fracture toughness. ... -
Nanoparticle delivery to the brain - By focused ultrasound and self-assembled nanoparticle-stabilized microbubbles
(Journal article, 2015)The blood–brain barrier (BBB) constitutes a significant obstacle for the delivery of drugs into the central nervous system (CNS). Nanoparticles have been able to partly overcome this obstacle and can thus improve drug ... -
Nanoparticle Dynamics in Composite Hydrogels Exposed to Low-Frequency Focused Ultrasound
(Peer reviewed; Journal article, 2023)Pulsed focused ultrasound (FUS) in combination with microbubbles has been shown to improve delivery and penetration of nanoparticles in tumors. To understand the mechanisms behind this treatment, it is important to evaluate ... -
Nanoparticle effect on Interfacial Properties related to Enhanced Oil Recovery
(Master thesis, 2015)This thesis takes a look at what has been done before with nanoparticles in EOR, and then experimentally investigates the effect of nanoparticles on fluid properties, in particular interfacial tension and wettability. The ... -
Nanoparticle Mediated P-Glycoprotein Silencing for Improved Drug Delivery across the Blood-Brain Barrier: A siRNA-Chitosan Approach
(Journal article; Peer reviewed, 2013)Background: Neonatal intermittent hyperoxia-hypoxia (IHH) is involved in the pathogenesis of retinopathy of prematurity. Whether similar oxygen fluctuations will create pathological changes in the grey and white matter ... -
Nanoparticle Mobility in Pig Small Intestine Mucus (PSIM) - Optimization of Methods used to study Diffusion of Nanoparticles through PSIM, and the Effect of G-block
(Master thesis, 2015)In this thesis, methods for studying diffusion of nanoparticles through pig small intestine mucus (PSIM) were to be studied and optimized. The nanoparticles used were different types of FluoSpheres® and also rhodamine ... -
Nanoparticle uptake by brain endothelial cells and focused ultrasound-mediated transport across the blood-brain barrier
(Doctoral theses at NTNU;2017:3, Doctoral thesis, 2016)More and more people in the world suffer from various brain diseases such as Parkinson’s disease, Alzheimer’s disease and brain cancer. One of the reasons it is so difficult to treat them is the blood-brain barrier (BBB) ... -
Nanoparticle-hydrogel composites: From molecular interactions to macroscopic behavior
(Journal article; Peer reviewed, 2019)Hydrogels are materials used in a variety of applications, ranging from tissue engineering to drug delivery. The incorporation of nanoparticles to yield composite hydrogels has gained substantial momentum over the years ... -
Nanoparticle-Mediated Wound Closure of Human Skin
