    Morphology of polystyrene-block-poly(acrylic acid) vesicles was imaged by various modes of scanning electron microscopy (SEM), including recently developed wet scanning transmission electron microscopy (wet-STEM) by means of which we were able to follow the decrease in the thickness of a liquid solvent layer around the vesicles during controlled evaporation of water from the sample. Results show that wet-STEM allows for imaging of nanosized polymeric particles in the presence of the solvent.
