Descrizione generale

PAMAM dendrimer, ethylenediamine core, generation 4.0 solution is a poly(amidoamine) that is categorized as a class of dendritic polymers which can be prepared by a two-step interactive reaction that forms generations around the central ethylenediamine core. It consists of nitrogen and amide as functional groups that are structured in regular “branched upon branched” pattern. It is majorly used as a high capacity chelating agent.

Applicazioni

PAMAM dendrimer, ethylenediamine core, generation 4.0 solution is used as a compacting agent to bring in the conformational changes in the DNA molecule. It can be attached on the cellulose substrate that acts as a biofunctional surface for potential applications in immonoassays. It is used in MRI contrast agents and in the condensation formation of silica nanospheres.

Peptide epitopes have been widely used to develop synthetic vaccines and immunotherapies. However, peptide epitopes may exhibit poor absorption or immunogenicity due to their low molecular weights. Conversely, fourth-generation polyamidoamine (G4-PAMAM) dendrimers are nonimmunogenic and relatively nontoxic synthetic nanoparticles that

Polyamidoamine (PAMAM) dendrimers are hyperbranched macromolecules which have been described as one of the most promising drug nanocarrier systems. A key process to understand is their cellular internalization mechanism because of its direct influence on their intracellular distribution, association with
