ABSTRACT
Alginate, a naturally occurring biopolymer derived from brown algae (kelp), has many
specific properties that have allowed it to be used as a matrix for the trapping and/or release of a
variety of biological agents. Alginate is a linear unbranched polysaccharide family that comprises
different amounts of 1,4-linked ?-D-mannuronic acid and ?-L-guluronic acid residues. Alginate is
a biomaterial that has found ample applications in drug delivery due to its favorable properties,
including thickening, gel forming, stabilizing and biocompatibility properties and biodegradability.
In addition, the low price, easy availability, natural origin, versatility and transitional properties of
sol-gel make alginate the ideal candidate for producing particles with different applications. The
oral route is preferred for drug administration by the most patients. The presence of a mucus layer
covering the entire gastrointestinal tract was exploited to extend the use of the oral route by
creating a method for the delivery of mucoadhesive drugs that demonstrated extended residence
time. Nanoparticles composed of alginate have emerged as one of the most extensively
characterized biomaterials used for drug delivery and targeting a set of administration routes.
Therefore, the development of synthetic derivatives has the ability to motivate the next generation
of alginate applications. This review article gives a comprehensive overview on its present use in
various fields of controlled drug delivery, biomedical applications and future possibilities.
