One of the challenges in the (bio)-nanotechnology field is development of nano-sized delivery systems comprising different functionalities. These systems enable to ship and to carry bioactive substances to pre-defined site and unload it in designed time and place. Layer-by-layer assembled capsules have been intensively studied in recent years owing to their ability to encapsulate a wide range of chemicals from complex biomacromolecules to small water soluble compounds, for their permeability to be modified and their responsiveness to different factors and functionalities to be tailored in one capsule entity. Current research leads to the fabrication of carriers with remote guiding and activation by optical, magnetic and ultrasound addressing, what envisages unique applications as multifunctional biomaterials, including intracellular entering and in-vivo delivery with remote controlled release of micropackaged chemicals. Release and encapsulation of materials by light and/or ultrasound and their navigation with magnetic field is a particularly interesting topic for chemical and biomedical applications. Microcapsules display a broad spectrum of qualities over other existing microdelivery systems such as high stability, longevity, versatile construction and geometry of micropackeging and a variety of methods to retain and release the substances.
