Abstract

Abstract To solve the traditional radiotherapy obstacles, and also to enhance the radiation therapy efficacy various radiosensitizers have been developed. Radiosensitizers are promising agents that under X-ray irradiation enhance injury to tumor tissue by accelerating DNA damage. In this report, silver-silver sulfide nanoparticles (Ag-Ag2S NPs) were synthesized via a facile, one-pot and environmentally friendly biomineralization method. Ag-Ag2S was coated with bovine serum albumin (BSA) in situ and applied as an X-ray sensitizer to enhance the efficiency of radiotherapy. Also, folic acid (FA) was conjugated to Ag-Ag2S@BSA to impart active targeting capability to the final formulation (Ag-Ag2S@BSA-FA). Prepared NPs were characterized by transmission electron microscopes (TEM), scanning electron microscope (SEM), dynamic light scattering (DLS), ultraviolet–visible spectroscopy (UV–Vis), X-ray diffraction analysis (XRD), and X-ray photoelectron spectroscopy (XPS) techniques. Results show that most of the NPs have well-defined uniform Janus structures. The biocompatibility of the NPs was then evaluated both in vitro and in vivo. A series of in vitro assays were performed on 4T1 cancer cells to evaluate the therapeutic efficacy of the designed NPs. In addition, the radio-enhancing ability of the NPs was tested on the 4T1 breast cancer murine model. MTT, live and dead cell staining, apoptosis, ROS generation, and clonogenic in vitro assays demonstrated the efficacy of NPs as radiosensitizers in radiotherapy. In vivo results as well as H&E staining tumor tissues confirmed tumor destruction in the group that received Ag-Ag2S@BSA-FA NPs and exposed to X-ray. The results showed that prepared tumor-targeted Ag-Ag2S@BSA-FA NPs could be potential candidates as radiosensitizers for enhanced radiotherapy.

  • Receptor-specific targeting approaches, including HER2-, CXCR4-, and folate-directed systems, were described in association with increased cellular uptake.

    “Receptor-specific targeting approaches, including HER2-, CXCR4-, and folate-directed systems, were described in association with increased cellular uptake [20,24,29,51,54,55].”

    The Results section (‘Cellular uptake and internalization efficacy’; page not provided) reports greater uptake of folic-acid-conjugated nanoparticles than unconjugated nanoparticles by 4T1 breast cancer cells and links this to folate receptors. The cited paper does not describe HER2- or CXCR4-directed uptake, so it supports only the folate-directed part of the sentence. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • As the field evolved, increasing emphasis was placed on functional modifications, including surface coatings, targeting ligands, biomimetic components, and therapeutic payloads, giving rise to multifunctional nanoplatforms capable of improving cellular uptake and integrating biological mechanisms of radiosensitization.

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.
