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 ...
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 ...
