Definition

Force-fluorescence spectroscopy generally refers to the combination of single-molecule manipulation technique with simultaneous single-molecule fluorescence measurement to characterize the mechanochemical properties of a macromolecule.

Basic Characteristics

On the one hand, single-molecule manipulation using scanning probe techniques, optical tweezers, and magnetic tweezers enables mechanical perturbation of a system at the single-molecule level. On the other hand, intermediates in time-dependent reactions that are otherwise difficult to study in conventional ensemble experiments due to the averaging over many molecules can now be observed and studied directly using single-molecule fluorescence techniques. The combination of single-molecule manipulation techniques with single-molecule fluorescence measurements can thus find many potential applications in biophysical research, for example, manipulation of a macromolecule, while observing...
