The reflection of my right hand in a mirror is a left hand that looks similar yet is very different from the right. Many natural structures such as proteins, climbing vines, and seashells exhibit the same property known as chirality. Some of these objects are clearly left-handed, some are right-handed, some are both. The ultimate origin of chirality is one of Nature's great mysteries. In this talk, I will discuss the general problem of determining the chirality of an object and how it impacts all branches of science.This lecture was recorded by Alain Goriely on 16th September 2025 at ...

[Ru(phen)2 (dppz)]2+ has been studied since the 1990s due to its ‘light-switch’ properties. It can be used as a luminescent DNA probe, with emission switched on through DNA binding. The luminescence observed is dependent on the solvent accessibility of the pyrazine nitrogen atoms, and therefore is sensitive to changes in both binding site of the cation and chromophore orientation. The compound is also chiral, and there are distinct differences between the enantiomers in terms of the emission behaviour when bound to a variety of DNA sequences. Whilst a number of binary DNA-complex X-ray ...
