Large macromolecular complexes are ubiquitous in biological media (e.g. protein complexes, membrane-bound complexes…). Specific biophysical techniques can be used to assess the interactions and structures of such complexes. Two independent systems were chosen as examples. The first one deals with the formation of protein coronas (protein/nanoparticle interactions) while the second system concerns virus encapsidation (protein/RNA interactions). Here, we can see how three techniques (isothermal titration calorimetry, cryoelectron microscopy, and small angle scattering) can be combined in order to answer fundamental questions.
