Abstract

This study demonstrates a novel nanostructured drug delivery system utilizing α‐Fe 2 O 3/CuO/CuFe 2 O 4 ternary nanocomposite for effective drug transport in sick tissues. Centella Asiatica plant extract was employed to synthesize the Fe 2 O 3/CuO/CuFe 2 O 4 nanocomposite via sol‐gel auto combustion technique. The structural and morphological characteristics of the nanocomposite were investigated by XRD, FT‐IR, SEM, EDX, and VSM for magnetic properties. The XRD analysis demonstrates the successful synthesis of Fe 2 O 3/CuO/CuFe 2 O 4 nanocomposite with an average crystallite size of 18.393 nm. The antioxidant and antifungal capabilities of this nanocomposite were assessed for its biological activity. A notable inhibitory zone was observed when tested against the Alternaria spp. and Bipolaris sorokiniana fungi. An IC 50 value of 109.88 μg/ml was found in the DPPH test, indicating that the nanocomposite exhibited remarkable antioxidant characteristics. Subsequently, metronidazole was encapsulated with a success rate of 55.53 % at pH 1.2, while at pH 7.4 it gained 57.83 %. The drug release of nanocomposite at pH 1.2 after 330 min was 43.41 % and at pH 7.4 after 300 min it was 52.3 %. The results indicate its potential as an excellent candidate for drug delivery. Furthermore, pH was found to be an effective catalyst in the drug loading and release processes.

  • Nanocomposites utilizing inorganic matrices such as porous silica or metal oxides are increasingly used to stabilize C. asiatica compounds and enable targeted dermal effects.

    “Nanocomposites utilizing inorganic matrices such as porous silica or metal oxides are increasingly used to stabilize C. asiatica compounds and enable targeted dermal effects.”

    From Centella asiatica (L.) Urb. in skin health and cosmeceuticals: mechanisms, clinical evidence, and advanced delivery systems (2025) · cites this paper as Sahara et al. 2025

    The Introduction and Conclusions describe a metal-oxide nanocomposite synthesized using C. asiatica extract as a green precursor, and the Methods identify metronidazole—not a C. asiatica compound—as the encapsulated drug. The paper does not show stabilization of C. asiatica compounds, use of porous silica, or targeted dermal delivery; its drug-loading tests concern gastrointestinal and blood/intestinal pH conditions. (LLM, conf=0.88)

    Experimental — accuracy not yet measured

  • Formulations with ZnO or magnetic oxides demonstrated antimicrobial, antioxidant, and angiogenic effects in diabetic wound and fungal models.

    “Similar formulations with ZnO or magnetic oxides demonstrated antimicrobial, antioxidant, and angiogenic effects in diabetic wound and fungal models (Wang et al. 2024; Sahara et al. 2025).”

    From Centella asiatica (L.) Urb. in skin health and cosmeceuticals: mechanisms, clinical evidence, and advanced delivery systems (2025) · cites this paper as Sahara et al. 2025

    The Results and Discussion sections report that the magnetic-oxide nanocomposite inhibited fungal growth and showed antioxidant activity in a DPPH assay. They do not report angiogenic effects or testing in a diabetic wound model; this paper also did not study a ZnO formulation. Thus Sahara et al. support the magnetic-oxide antifungal and antioxidant part of the jointly cited sentence, but not those additional effects or settings. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
