To resolve an object in an electron microscope, the wavelength of the electrons must be close to the diameter of the object. What kinetic energy, k , must the electrons have in order to resolve a protein molecule that is 8.60 nm in diameter? Take the mass of an electron to be 9.11×10−31 kg .

I think the best answer to this is when the object is in high temperature and intense pressure that could make the molecule move and active. I hope you are satisfied with my answer and feel free to ask for more if you have further question and clarification.
