9-Acridinemethanamine and Acridine-9-Carboxaldehyde as Potential Fluorescence Lifetime pH Indicators
Totland, Christian; Thomas, Peter; Holst, Bodil; Akhtar, Naureen; Hovdenes, Jostein; Skodvin, Tore (Journal article; Peer reviewed, 2020)A significant challenge concerning the development of fluorescence lifetime (FL) based pH sensors is the paucity of fluorophores with sufficiently large FL variation with pH. Acridine is amongst the indicators with highest ... -
Fluorescence intensity and fluorescence lifetime measurements of various carbon dots as a function of pH
Szapoczka, Wiktoria Karolina; Truskewycz, Adam Leo; Skodvin, Tore; Holst, Bodil; Thomas, Peter James (Journal article; Peer reviewed, 2023)Measurement and monitoring of pH are essential in both the industry and academia. It is therefore important to continue developing novel, low-cost pH sensors that provide increased accuracy over long periods of time. ... -
Impact of fish protein concentrate on apparent viscosity and physical properties of soy protein concentrate subjected to thermomechanical treatment
Ahmad, Rafiq; Oterhals, Åge; Xue, Ying; Skodvin, Tore; Samuelsen, Tor Andreas (Peer reviewed; Journal article, 2019-04-30)The aim of this research was to investigate the plasticizing and binding effect of fish protein concentrate (FPC) on soy protein concentrate (SPC) with the use of a capillary rheometer with pre-shearing capabilities. A ... -
Ratiometric Fluorescent pH Sensing with Carbon Dots: Fluorescence Mapping across pH Levels for Potential Underwater Applications
Szapoczka, Wiktoria Karolina; Olla, Chiara; Carucci, Cristina; Truskewycz, Adam Leo; Skodvin, Tore; Salis, Andrea; Carbonaro, Carlo Maria; Holst, Bodil; Thomas, Peter James (Journal article; Peer reviewed, 2024-09-02)Ocean acidification has become a major climate change concern requiring continuous observation. Additionally, in the industry, pH surveillance is of great importance. Consequently, there is a pressing demand to develop ... -
Transparent, Antibiofouling Window Obtained with Surface Nanostructuring
Szapoczka, Wiktoria Karolina; Larsen, Viljar H.; Böpple, Hanna; Kleinegris, Dorinde Mechtilde Meike; Diao, Zhaolu; Skodvin, Tore; Spatz, Joachim P.; Holst, Bodil; Thomas, Peter James (Journal article; Peer reviewed, 2024)Biofouling is one of the key factors which limits the long-term performance of seawater sensors. Common measures to hinder biofouling include toxic paints, mechanical cleaning and UV radiation. All of these measures have ... -
The use of surfactant-filled mesoporous silica as an immobilising medium for a fluorescence lifetime pH indicator, providing long-term calibration stability
Totland, Christian; Thomas, Peter; Holst, Bodil; Hovdenes, Jostein; Akhtar, Naureen; Skodvin, Tore (Peer reviewed; Journal article, 2019-11-14)Surfactant filled mesoporous silica is applied as a matrix for immobilizing the fluorescence lifetime pH-indicator acridine. We demonstrate that this type of encapsulation provides a stable and uniform chemical environment ...
