Time-resolved studies of biological macromolecules have yielded unprecedented details about structural transitions during biological function. Furthermore, these experiments have driven the development of new methods for sample triggering, delivery and data collection, as well as the commissioning of specialized experimental end-stations. While proteins that bind natural chromophores have been a major interest in the field, there is now increasing interest to broaden the ability of time resolved experiments to other targets. New strategies (including mixing, electric fields, temperature and pressure jumps, and syntheses of caged substrates) will be discussed along with potential classes of macromolecules that can now be studied by time resolved methods. A discussion of how these new strategies can be employed at specialized experimental end-stations at Synchrotrons and Free Electron Lasers will give the users an overview of current data collection capabilities and point the way forward for future developments.
