However, when the concentration of the ROS exceeds, supplementation with potential antioxidants with fewer side effects plays a role in their elimination. In this regard, bio-nanocomposites, due to their eco-friendly nature, are being largely explored. This study uses <em>in vitro</em> DPPH and ABTS free radical scavenging assay methodologies to evaluate the antioxidant potential of gum kondagogu (GK) based monometallic [Silver (Ag), Gold (Au), and Palladium (Pd)], bimetallic (Ag-Au, Ag-Pd, and Au-Pd) and trimetallic (Ag Au Pd) nanocomposites. The known antioxidant, ascorbic acid, served as the positive reference standard, while native gum was utilised as the negative control. The per cent free radical scavenging activities of GK-based nanocomposites by DPPH (2–20 µg mL⁻¹) and ABTS (1–5 µg mL⁻¹) assays were: AgNPs (68.36; 85.33), AuNPs (52.34; 58.63), PdNPs (72.19; 72.09), AgAuPdNPs (84.69; 67.90), Ag-Au (54.07;76.24), Ag-Pd (67.29;85.87) and Au-Pd (95.0; 79.30), respectively. Among all the nanocomposites, the bimetallic exhibited the highest antioxidant potential, followed by the trimetallic and the monometallic in a concentration-dependent manner. Further, the AuPdNPs exhibited the highest (95.0 %) scavenging activity at 5 µg mL⁻¹ concentration and also the lowest IC₅₀ values of 0.87 ± 0.08 µg mL⁻¹ in DPPH and 1.99 ± 0.10 µg mL⁻¹ in ABTS assays. The present study demonstrated the antioxidant ability of the monometallic, bimetallic and the trimetallic nanocomposites and suggested that the presence of palladium greatly enhanced the antioxidant efficacy due to their synergistic properties.</div></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":"8 ","pages":"Article 100188"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Graphene quantum dots (GQDs) and their derivatives have shown promising characteristics for precisely transporting anticancer drugs to tumor cells. Herein, grapheneol quantum dots (GQDs) derived from poly (L-lactic acid) and decorated with folic acid were prepared, for the first time, via a sonochemical approach. The synthesized GQDs were functionalized with folic acid to improve their affinity for folate-positive breast cancer cells, thereby extending their circulation time. Ultimately, these GQDs were loaded with the anticancer agent methotrexate (MTX) to mitigate its adverse effects. Transmission electron microscopy (TEM) and atomic force microscopy confirmed the formation of grapheneol quantum dots with a lateral size of around 2.1 ± 0.2 nm. The UV–vis spectrophotometer measurements showed that the GQDs exhibit a strong quantum confinement effect with an optical band gap energy around 3.2 eV. The photoluminescence measurements showed that the GQDs exhibited high luminescence with intense blue emission and a quantum yield exceeding 72 %. The Raman, X-ray photoelectron spectroscopy, and FTIR measurements revealed that the folic acid decorated the surface of the GQDs. The hydrodynamic light scattering (DLS) and zeta potential measurements indicated that the lateral size of GQDs increases from 2.1 nm to 10 nm, confirming the attachment of the folic acid to the surface of the GQDs. However, the zeta potential of the GQDs changed from −7.6 meV to −14.3 meV, implying the enhancement of the dispersion stability of the GQDs due to the presence of folic acid on their surfaces. The FA-decorated GQDs were used as nanocarriers for the pharmaceutical cancer drug (methotrexate).
