You are about to preforem a microscopy experiment in which you will monitor the fluoresence from a single lysozyme molecule. The spantial resolution of the microscope is 1μm. You intend to monitor the diffusion using a camera that is capable of one image every 60 s. Is this imaging rate of the camera sufficent to detect the diffusion of a single lysozyne protein over a length of 1μm
