Abstract-
Dendrimers belong to a novel and exciting class of highly branched
three-dimensional polymer in which growth emanates from a central core
molecule such as ammonia, ethylenediamine, and polydiamine or benzene
tricarboxylic acid chloride. Compared with traditional linear
polymers, dendrimers have much more accurately controlled structures
with a globular shape, a single molecular weight rather than a
distribution o molecular weight and a large number of ‘controllable’
peripheral functionalities.
In
recent years, there has been an increasing interest in the field of
dendrimers. In particular, the intrinsic connectivity of the dendrimer
such as the multivalency of the focal core and the multiplicity of the
branches, both controlling the geometrical rate of growth, or the
dendritic generation, plays a crucial role and influences at various
stages the subtle relationships between the supermolecular structure
and the mesophase structure. Stability Dendrimers belong to a novel and
exciting class of highly branched three-dimensional polymer in which
growth emanates from a central core molecule such as ammonia,
ethylenediamine, and polydiamine or benzene tricarboxylic acid chloride. Compared
with traditional linear polymers, dendrimers have much more accurately
controlled structures with a globular shape, a single molecular weight
rather than a distribution of molecular weight and a large number of
‘controllable’ peripheral functionalities. They are truly nanoscale
molecules with sizes ranging from 10–30 Å. and the excitement
associated with this class of polymers is mainly because of their
applications as synthetic vector systems for gene delivery.
Polyaminodiamine (PMAM) is a promising polycationic polymer from this
class that can form complexes with the negatively charged nucleic
acids; additionally, the surface positive charge can interact and fuse
with phospholipids of the cell membrane, thereby facilitating the
translocation of DNA into cells.
