ABSTRACT

New class of microobjects synthesized by Layer-by-Layer assembly method has been observed. These are polyelectrolyte nanocomposite microcapsules. This chapter describes the approaches and methods of nanocomposite capsule fabrication. A laser beam influences only single microcapsules. Thus microwave radiation and ultrasound are suggested to be used for remote capsules activation. The opportunity of inclusion of various substances inside microcapsules is the most interesting functionality of the structures. The simplest way of inclusion of inorganic nanoparticles in the microcapsule shells is their adsorption. Thus, a usual layer-by-layer assembly technique is used to embed nanoparticles in a capsule shell structure. Chemical synthesis can even provide polyelectrolyte capsules with desired properties for further biomedical or drug delivery applications, and also as catalyzed or fermentative microreactors. The investigation of nanoparticles aggregation ratio influence on planar polyelectrolyte assemblies and microcapsules properties was carried out in paper.
