Nanotechnologies
are bringing new horizons in all over the material arena.
Particularly, applications in food and medical areas in where
controlled release technologies are expecting to reduce famines,
improve health and enhance life quality. The main strategy in the
Bio/fields is known as self assembly and based on the creation of new
functional structures produced by the interaction of two or more
molecules, which are showing different physicochemical and biological
properties. In that field, biological molecules are palying a crucial
role because their regio-, enantio- and stereo-selectivity, which
allows to get a myriad of structures and functions. Amongst them,
biopolymers and enzymes could cover many different function and roles
in the development of new controlled release devices. Smart
biopolymers can be used to reach different portions of the intestine
for the delivery of therapeutic labile molecules, e.g.
antibiotics, cytostatics to protect them from enzymatic degradation
and the harsh enviromental condition of the stomach. Likewise,
patches based on biopolymers to slowly release hormones, enzymes
and/or antimicotic drugs over the skin. Nanotechnology-functionalized
foods can add high nutritional value by incorporating unstable
molecules (like antioxidants, pro-vitamins) to enhance food flavor
and taste which specially relevant in elderly people, newborns and
children.
