The structure, properties, synthesis, negligible toxicity, and surface modification of PAMAM (polyamidoamine dendrimers) are all discussed in this review. The properties of supramolecular PAMAM dendrimers in nanopolymer science have shown great progress in delivering medicines. A divergent strategy was used to construct a Generation four (G4.0) PAMAM dendrimer with an ethylenediaminetetraacetic acid core and repeating units of acrylic acid and ethylenediamine. PAMAM dendrimers have an amidoamine repeat branching architecture that starts with an ethylene diamine initiator core. A generation [G] is a set of branching steps that follow each other. Drug molecules can be transferred either as covalently bonded to the functional groups on the dendrimer surface or by forming non-covalent complexes with dendrimers. Full-generation PAMAM dendrimers are terminated with amine surface [G0, G1, G2, G3, G4], whereas halfgeneration dendrimers are terminated with carboxylate [G1.5, G2.5, etc.]. PAMAM dendrimers appear to have negligible toxicity and immunogenicity, as well as favorable biodistribution; according to the current study, they can improve drug solubility, prevent drug degradation, increase circulation time, and potentially target drugs. According to the characterization study, they exhibit strong lipophilic qualities, allowing them to easily pass the blood-brain barrier. Due to the cheaper polydispersity index of dendrimers, they possess greater stability, and the void spaces of dendrimers are accessible for drug loading. The existence of a duplet functional group on the dendrimers enables appending vectors, ligands and devices to target drug delivery in the body.

Keywords: Dendrimers, nanoparticles, covalently, toxicity, PAMAM, cosmetics.
