A Review of Optical Methods for Continuous Glucose Monitoring
Jernelv, Ine Larsen; Milenko, Karolina Barbara; Fuglerud, Silje Skeide; Hjelme, Dag Roar; Ellingsen, Reinold; Aksnes, Astrid (Journal article; Peer reviewed, 2018)Frequent glucose monitoring is a fundamental part of diabetes management, and good glucose control is important for long-term health outcomes. New types of electrochemical sensors that allow for continuous glucose monitoring ... -
Infrared measurements of glucose in peritoneal fluid with a tuneable quantum cascade laser
Jernelv, Ine Larsen; Hjelme, Dag Roar; Aksnes, Astrid (Peer reviewed; Journal article, 2020)Fast and accurate continuous glucose monitoring is needed in future systems for control of blood glucose levels in type 1 diabetes patients. Direct spectroscopic measurement of glucose in the peritoneal cavity is an ... -
Infrared Spectroscopy with a Fiber-Coupled Quantum Cascade Laser for Attenuated Total Reflection Measurements Towards Biomedical Applications
Jernelv, Ine Larsen; Strøm, Karina; Hjelme, Dag Roar; Aksnes, Astrid (Journal article; Peer reviewed, 2019)The development of rapid and accurate biomedical laser spectroscopy systems in the mid-infrared has been enabled by the commercial availability of external-cavity quantum cascade lasers (EC-QCLs). EC-QCLs are a preferable ... -
Mid-Infrared Laser Spectroscopy for Glucose Sensing
Strøm, Karina (Master thesis, 2019)For å kunne lage en enhet for kontinuerlig glukosemåling som har lang levetid er det ønskelig med en forbedret spektroskopi målemetode for å kunne detektere glukose. En slik enhet vil kunne forbedre livskvaliteten til ... -
Mid-infrared spectroscopy with a fiber-coupled tuneable quantum cascade laser for glucose sensing
Jernelv, Ine Larsen; Strøm, Karina; Hjelme, Dag Roar; Aksnes, Astrid (Peer reviewed; Journal article, 2020)A fiber-coupled transmission spectroscopy setup using a pulsed external-cavity quantum cascade laser (EC-QCL, 1200-900 cm−1 ) has been developed and demonstrated for measurements of aqueous solutions. The system has been ... -
Optimisation of Positron-Positronium Conversion and Positronium Laser Excitation
Jernelv, Ine Larsen (Master thesis, 2015)The AEgIS collaboration (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) at CERN has as its goal to directly measure the Earth's gravitational force on antimatter for the first time. Neutral antihydrogen atoms ... -
Signal enhancement in microstructured silicon attenuated total reflection elements with quantum cascade laser-based spectroscopy
Jernelv, Ine Larsen; Høvik, Jens; Hjelme, Dag Roar; Aksnes, Astrid (Peer reviewed; Journal article, 2020)Sensors in mid-infrared spectroscopy based on attenuated total reflection (ATR) sensing with internal reflection elements (IREs) facilitate easier measurements of aqueous solutions or other opaque analytes. Micromachined ...
