Ultrafast processes in light-absorbing proteins have been implicated in the primary step in
the light-to-energy conversion and the initialization of photoresponsive biological functions …

Photoinduced reactions play an important role in the photocycle of fluorescent proteins from
the green fluorescent protein (GFP) family. Among such processes are photoisomerization …

The photoisomerization reaction of a fluorescent protein chromophore occurs on the ultrafast
timescale. The structural dynamics that result from femtosecond optical excitation have …

Chromophores absorb light in photosensitive proteins and thereby initiate fundamental
biological processes such as photosynthesis, vision and biofluorescence. An important goal …

Synthetic hydrogels are widely used as biomimetic in vitro model systems to understand
how cells respond to complex microenvironments. The mechanical properties of hydrogels …

Development of single-molecule localization microscopy (SMLM) has sparked a revolution
in biological imaging, allowing “super-resolution” fluorescence microscopy below the …

Photoreversible on–off recording of red persistent room‐temperature phosphorescence
(RTP) is demonstrated. Host–guest materials composed of a persistent phosphorescent …

Reversibly switchable fluorescent proteins (RSFPs) serve as markers in advanced
fluorescence imaging. Photoswitching from a non-fluorescent off-state to a fluorescent on …

Dynamical changes in protein structures are essential for protein function and occur over
femtoseconds to seconds timescales. X‐ray free electron lasers have facilitated …

Time-resolved electronic spectroscopy has grown into a technique that provides hundreds to
thousands of electronic spectra with femtosecond time resolution. This enables complex …
