And so now, to separate these amino acids in solution from the liposome of interest, all we have to do is undergo some type of purification process. So, for instance, we can use dialysis or gel filtration chromatography to basically separate and isolate those liposomes of interest. And then we can, for example, use those liposomes to basically study the rate at which these amino acids actually leave that cell membrane. And what that tells us is it gives us the permeability of the cell membrane to that particular amino acid. And we can conduct many different types of experiments that basically provide us with information about different aspects, different properties of that membrane, such as the permeability of that membrane. Now, we can also use them to basically deliver drugs and other things to patients.
