The ability to manipulate the structure and function of promising nanosystems via energy
input and external stimuli is emerging as an attractive paradigm for developing …

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 …

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 …

Biological systems are characterized by a level of spatial and temporal organization that
often lies beyond the grasp of present day methods. Light-modulated bioreagents, including …

Light is unsurpassed in its ability to modulate biological interactions. Since their discovery,
chemists have been fascinated by photosensitive molecules capable of switching between …

The photoinduced isomerization of azobenzene between the extended (trans) and compact
(cis) conformations is reversibly triggered by light of two differing wavelengths. The resulting …

Reversible optical control of protein structure and function offers the possibility of probing
and manipulating individual proteins within the complex environment of a living cell. As a …

Coating of surfaces by RGD peptides is well-known. Herein we describe the possibility to
switch cell adhesion properties by changing the distance and orientation of the RGD …
