Initial work began with testing various starches for encapsulation properties. Low viscosity, stable starch dextrins were first evaluated versus gum arabic for encapsulation efficiencies. Dispersions of corn and tapioca dextrins were used to encapsulate single fold orange oil.

Some other capsules have been described in which both complimentary functions, carboxylic acids and nitrogen-containing aromatic rings, are respectively attached to the rims of two bowl-shaped molecules. Reinhoudt has prepared selfassembling, multi-hydrogen bonding molecular capsules in which a calix[4]arene substituted with four carboxylic functions at the upper rim interacts with a complimentary calix[4]arene with four pyridines attached to the lower rim. These capsules have been identified by H-NiMR, IR and VPO measurements but encapsulation properties have not been reported [106]. 

Cold-set whey protein gels obtained by addition of calcium ions to preheated whey proteins have been used to deliver iron (Remondetto et al. 2002). By modulating the conditions of formation, gels with different microstructures (particulate or filamentous) were formed with different encapsulating properties. Filamentous whey protein gels were more efficient than particulate gels in delivering bioavailable iron to the intestine, as less iron was released at acidic but more at alkaline pH (Remondetto et al. 2004).

The physical context concept in the conceptual model is extended to describe the behavior of plastics in the form of pellets through the class solid state condition which encapsulates properties such as pellet type. This part of the implementation model concerns the mathematical modeling of some of the properties of polymers, which correspond to their djmamic or flow behavior. A class for a concrete mathematical model not only holds declarative information such as the list of parameters, but also provides a method for calculating the value of the property modeled. This method requires an implementation which is usually different from the one for another mathematical model. Therefore, mathematical models are organized in this application through further classification. 

In the early days of this research field also covalent based capsules were assigned as supramolecular capsules because of their encapsulation properties. However, because of the developments of the last decade we designate here only non-covalent based capsules as supramolecular capsules .

The encapsulation performances of combining AI2O3 and parylene-C were compared to those of the individual layers of parylene-C or AI2O3. The bilayer coating exhibits superior encapsulation properties. 

The emergence of bioactive food compounds (neutraceuticals) with health benefits provides an excellent opportunity to improve pubUc health. The incorporation of bioactive compounds, such as peptides and vitamins, into food systems holds much promise in the development of innovative functional foods that may have physiological benefits or reduce the risk of diseases. Compared to pharmaceutical applications, little work has been done on the encapsulation properties of chitosan nanoparticles for the oral administration of neutraceuticals in healthy food. More recently, chitosan has been identified as a versatile biopolymer for a broad range of health and food applications because of its safety and nontoxicity in human beings. Because chitosan matrix is not stable at very low pH, modificatimis to the chitosan micro- or nanoparticles might be able to protect them.

Cyanoacrylate pol5uners are also extensively used in the production of encapsulated colloidal nanoparticles for targeted drug delivery systems and are particularly useful in the treatment of certain cancers (64). Their good encapsulation properties, low toxicity, and satisfactory biocompatibility make them attractive for this application. By forming amphiphilic copolymers of cyanoacrylate and ethylene oxide, the therapeutic activity of entrapped compoimds can be enhanced. The copolymer functions to prolong the circulation lifetime of the nanoparticles after they have been introduced into the bloodstream (65).
