Molecular photoswitches enable dynamic control of processes with high spatiotemporal
precision, using light as external stimulus, and hence are ideal tools for different research …

Controlling the conformation and activity of biomolecules in a reversible manner is a
fascinating challenge (1-3) that has an outstanding potential for the study of and interference …

The photoisomerization of azobenzene has been known for almost 75 years but only
recently has this process been widely applied to biological systems. The central challenge of …

In this review, we explore different approaches for introducing bioactivity into poly (ethylene
glycol)(PEG) hydrogels. Hydrogels are excellent scaffolding materials for repairing and …

Organic molecules as well as metal complexes may exist as several geometric isomers1
which display distinct physical properties and chemical reactivities. A molecule containing …

The design of molecular switches and trigger elements offers a formidable challenge on the
road toward miniaturization in future technology1-3 and the development of materials for …

Light-powered molecular machines are conjectured to be essential constituents of future
nanoscale devices. As a model for such systems, we have synthesized a polymer of bistable …

The last few years have witnessed significant advances in the use of light as a stimulus to
control biomolecular interactions. Great efforts have been devoted to the development of …

Protein–protein interactions are vital to biological processes, but the shape and size of their
interfaces make them hard to target using small molecules. Cyclic peptides have shown …

Femtosecond transient absorption measurements of the photoisomerization of azobenzene
excited at 435 nm in the long-wavelength formation with a dominating 170 fs and a weak 2 …
