Abstract: Abstract: Compared to other nano polymers, dendrimers have novel three-dimensional, synthetic
hyperbranched, nano-polymeric structures. These supramolecular dendritic structures have a high
degree of significant surface and core functionality in the transportation of drugs for targeted therapy,
specifically in host-guest response, gene transfer therapy, and imaging of biological systems.
However, there are conflicting shreds of evidence regarding biological safety and dendrimers toxicity
due to their positive charge at the surface. It includes cytotoxicity, hemolytic toxicity, haematological
toxicity, immunogenicity, and in vivo toxicity. Surface modification of the dendrimer group
is one of the methods to resolve these issues. This review aimed at investigating different strategies
that can reduce toxicity and improve the biocompatibility of different dendrimers. From that viewpoint,
we broaden the structural and safe characteristics of the dendrimers in the biomedical and
pharmaceutical fields.
