Right: Polymeric capsules encapsulate the organic active ingredient in a core-shell commercial product.
Left: Capsules remain aggregated in a polymeric phase within the water environment. The cavity of the capsules can be observed when imaging at higher acceleration voltages.

Silver nanoparticles synthesized by reduction of silver ions in water, dried sample on the left and wet on the right. Imaging the dried suspension will not reflect the true level of aggregation. The image of the dried suspension shows a high degree of aggregation as a result of the drying process. The particles in the WETSEM image on the right are mostly isolated, with the existing aggregates much smaller than those seen on the left.
