BACKGROUND Conformational changes are essential for the correct functioning of
biological macromolecules. Time-resolved x-ray crystallography extends an extremely …

Ultrafast spectroscopy techniques use sequences of ultrashort light pulses (with femto-to
attosecond durations) to study photoinduced dynamical processes in atoms, molecules …

Since determination of the myoglobin structure in 1957, X-ray crystallography, as the
anchoring tool of structural biology, has played an instrumental role in deciphering the …

X-ray crystallography is an established method for studying the structure of proteins and
other macromolecules. As the importance of proteins grows, researchers in many fields have …

With the recent advances in ultrabright electron and x-ray sources, it is now possible to
extend crystallography to the femtosecond time domain to literally light up atomic motions …

Block copolymer micelles are water-soluble biocompatible nanocontainers with great
potential for delivering hydrophobic drugs. An understanding of their cellular distribution is …

Inspired by the high photoconversion efficiency observed in natural light-harvesting systems,
the hierarchical organization of molecular building blocks has gained impetus in the past …

Photolabile protecting groups enable biochemists to control the release of bioactive
compounds in living tissue.'Caged compounds'(photoactivatable bioagents) have become …
