Preparation and characterization of dendrimer-modified graphene oxide nanoparticles for loading and releasing of doxorubicin: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


Doxorubicin is an anticancer drug recognized for quite a lot of cancers. As a focused drug, it’s loaded onto branched graphene oxide nanoparticles (GONPs). On this analysis, polymeric coatings containing vinyl alcohol bonded of the fifth technology of dendrimers containing methyl methacrylate (MMA) and ethylenediamine (EDA) teams act as a responsive polymer.

The precursors are polymerized to kind the dendrimer coating because the final service on the graphene oxide floor. Then polyvinyl alcohol (pH-sensitive polymer) coating is used on the floor of branched graphene oxide. When the nanoparticles carry the drug, they aren’t acknowledged by the immune system. The quantity of drug launch is elevated. The typical dimension of the ultimate product is 30 nm. It’s characterised by FTIR, TGA, XRD, and SEM-EDX to analyze completely different adsorption properties. A few of the bodily parameters of the adsorption course of, similar to pH, time, and temperature for doxorubicin are investigated utilizing the ultimate adsorbent. The drug launch by the adsorbent coated with pH-sensitive polymer is greater than when the polymer coating was not utilized on the nanoparticle. Drug launch exams confirmed pH sensitivity conduct of graphene oxide/dendrimer/polyvinyl alcohol (GO/dendrimer/PVA), with %99.7 drug launch at acidic (pH = 5.6) and %59 at impartial (pH = 7.four) circumstances, that is means within the pH of a tumorous cell and the blood pH stage, respectively.
