Schematic structure of a section of a fluorous emulsion nanoparticle. (A) The original lineal diblock copolymer forms a polymer shell around the fluorous particle that allows easy diffusion of anesthetic molecule in solution. This phenomenon leads to the growth of the nanoparticles volume and destabilizes the emulsion. (B) The use of a smaller poly(ethylene glycol) and a much bulkier fluorous tail leads to a more compact polymer shell around the fluorous nanoparticle. The rate of diffusion of anesthetic molecules in solution is reduced and the emulsion is stabilized.
