![]() Structural, morphological, and compositional properties were investigated by the physicochemical characterization method.Through the green bio-synthesis method the gold-silver core-shell nanoparticles (Au-Ag NPs) synthesised by Garcinia mangostana crude peels extract as a reducing and stabilising agents.These findings suggest that Au-AgNPs system can be used as a potent nanocarrier to combat cancerous cells by offering additional anticancer properties to the loaded drug. The PCA-loaded Au-AgNPs also showed a better selectivity towards HCT116 compared to CCD112 colon normal cells when tested at the same concentrations. Up to 80% inhibition of HCT116 cells was observed after the treatment of PCA-loaded Au-AgNPs at 15.63 μg/ml. In HCT116 colon cancer cells, PCA-loaded Au-AgNPs (IC 50 = 10.78 μg/ml) showed higher inhibitory action than the free PCA (IC 50= 148.09 μg/ml) and Au-AgNPs alone (IC 50= 24.36 μg/ml). ![]() Plant-based drug, protocatechuic acid (PCA) was loaded on the Au-AgNPs to investigate their anticancer activity. The size of Au-AgNPs was 38.22 ± 8.41 nm and was mostly spherical in shape. A complete coating was observed through transmission electron microscopy (TEM) when the ratio of AuNPs and AgNPs was 1:9. Gold-silver core-shell nanoparticles (Au-AgNPs) were synthesized through seed germination process in which gold nanoparticles acted as the seed. This study aimed to synthesize core-shell nanoparticles via green method which utilised crude peels extract of Garcinia mangostana as reducing and stabilising agents for drug delivery. Core-shell nanoparticles have emerged as good candidate for anticancer treatment. Hence, there is an urgent need to discover a more target-specific therapeutic agent to overcome this problem. ![]() Current treatment and anticancer drugs cannot specifically target the cancerous cells, thus causing toxicity towards surrounding non-cancer cells.
