I have a question for you. Let's say you have a solution and you want to find out the distribution of particles within it. Of course, the typical assumption is that particles are evenly distributed in a solution, but imagine that there are forces acting on a particle such that that might not be the case. Then, it is a non-trivial issue as to the distribution of the particles. So, what I want to know is if there is a way to determine the THREE-DIMENSIONAL distribution of particles in solution. Would 3D fluorescence spectroscopy work? Thanks!
