Mariya’s and Sergey’s paper was published in Langmuir. This paper shows that the quantity of encapsulated charged molecules can be controlled through the interactions with the scaffold that is used to create nanocapsules. By controlling these interactions either through changing the formulation of surfactant scaffold or adjusting the pH of the solution, Mariya and Sergey learned how to increase or decrease the concentration of encapsulated molecules. They work offers greater control on the composition of nanocapsule-based devices.
