Feynman was correct when he predicted “There's Plenty of Room at the Bottom.” Since Feynman's talk, given at Caltech in 1959, there has been an explosion of research in the ever-shrinking areas of nanoscience. A nanometer (nano—Greek for dwarf) is one billionth of a meter, or ten times the size of an individual hydrogen atom. Since the mid-1980s, there has been a substantial increase in interest over the creation and use of nanocapsules, a subset of nanoparticles. Nanocapsules have a number of potential applications, some of which include dye dispersants, nanoreaction vessels, and encapsulation media for fragrances, flavors, or drugs. This article will discuss the specific case of oil-filled nanocapsules. Such structures readily encapsulate lipophilic/hydrophobic and oil-soluble compounds, allowing them to be dispersed and transported through aqueous media.
