MS Frei, P Hoess, M Lampe, B Nijmeijer… - Nature …, 2019 - nature.com
Photoactivatable fluorophores are important for single-particle tracking and super-resolution
microscopy. Here we present a photoactivatable fluorophore that forms a bright silicon …

Live-cell fluorescence lifetime multiplexing using synthetic fluorescent probes

MS Frei, B Koch, J Hiblot, K Johnsson - ACS Chemical Biology, 2022 - ACS Publications
Fluorescence lifetime multiplexing requires fluorescent probes with distinct fluorescence
lifetimes but similar spectral properties. Even though synthetic probes for many cellular targets …

[HTML][HTML] A general method for the development of multicolor biosensors with large dynamic ranges

…, A Edenhofer, L Barck, MC Huppertz, MS Frei… - Nature Chemical …, 2023 - nature.com
Fluorescent biosensors enable the study of cell physiology with spatiotemporal resolution;
yet, most biosensors suffer from relatively low dynamic ranges. Here, we introduce a family of …
