Single Molecule Biophysics

Dr Liming Ying, Group Leader

 

The key processes of life occur in the noisy and far from equilibrium cellular environment, which is characterised by heterogeneity and stochastic fluctuation. To unravel this complexity, biology requires new physical concepts and methodologies. One promising approach is to measure the properties and dynamics of biological molecules, macromolecular machines, and cellular properties at the single molecule level. Single molecule approaches have the advantages of avoiding ensemble averaging, observing transient intermediates and heterogeneity (both static and dynamic), and they have started revolutionising the way many biological questions are addressed. Our group is interested in the development and applications of single molecule methodologies, in particular novel fluorescence imaging methods, to monitor the behaviour and properties of individual biological molecules, molecular complexes and molecular machines, in vitro and in living cells. We are currently working in the following specific areas:
