Colloidal nanoencapsulation

While the hterature has demonstrated the viabihty of nanoencapsulation via miniemulsion technology, a great many issues remain. These include the use of surfactant systems to stabihze the solid colloidal particles and bring them into the monomer droplets, uniformity of encapsulation (a uniform [small] number of solid particles per polymer particle for a minimum number of polymer particles, not including the encapsulated sohd), and complete coverage of the solids by the resultant polymer coating.

Although many areas of nanotechnology do not directly deal with colloidal dispersions (such as nanoelectronic devices [70]), other areas do, such as the use of colloidal ink dispersions in robocasting to build near-nanometre scale of three-dimensional structures. The possible use of nanoemulsions in nanoencapsulation for intravenous delivery and in medical diagnostics has already been mentioned in Sections 14.4 and 14.5. Nanoencapsulation by means other than just emulsification continues to be developed. Some other application areas include the following ...
