Layer-by-layer assembled capsules are owing to their ability to encapsulate a wide range of chemicals, 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 invivo. Submicron sized capsules are good model to mimicking bio-chemical processes in a confined geometry imitating cell organelles, whilst delivered inside cell and tissues the capsules could serve as intracellular reporter or enzymatic reactor.
