Abstract

Cancer is one of the most common health problems responsible for outnumbered deaths worldwide. Nanomedicine plays an important role in developing alternative and more effective treatment strategies for cancer theranostics. However, the toxicity, high cost and nanoparticles (NPs) production complexity are some of the major issues that obstruct the use of existing nanomedicine. Recently, the green synthesis of biogenic NPs from plants and microbial sources has become an emerging field due to their safer, eco-friendly, simple, fast, energy efficient, low-cost and less toxic nature. Interestingly, NPs play a key role in diagnosis of tumor at the initial stage by allowing cellular visualization. Furthermore, prospective applications of green NPs include magnetically responsive drug delivery, anti-cancer activity, photo-thermal therapy and bio-imaging. The present review provides perspective on the use of anti-cancer green bionanomaterials with a focus on their present status and future prospects in the theranostics of cancer.

Written from the paper’s full text.

TL;DR

This narrative review argues that green-synthesized metal bionanomaterials from plants and microbes are promising, safer, lower-cost alternatives for cancer theranostics, with reported in vitro anticancer activity and imaging/drug-delivery applications. However, clinical translation remains limited by incomplete mechanistic understanding, toxicity/immunological concerns, protein corona effects, and manufacturing/scale-up challenges.

Key findings

  • Green synthesis of metal nanoparticles (Au, Ag, Cu, Ti, Zn, Fe) is reported from plant extracts, algae, bacteria, actinomycetes, fungi, and yeast; phytochemicals such as flavonoids, polyphenols, proteins, and alkaloids are proposed to reduce and cap metal ions, while microbial nitrate reductase is implicated in extracellular fabrication.
  • In vitro anticancer activity is reported against many cancer cell lines, often dose-dependent, with some selectivity examples: biogenic AgNPs showed IC50 27.75 µg/mL against SMMC-7721 hepatoma vs 81.39 µg/mL in normal HL-7702 liver cells; AuNPs inhibited HeLa with IC50 100 µg/mL vs 300 µg/mL in normal bone marrow mesenchymal stem cells; EPS-stabilized FeONPs had IC50 62.946 mg/mL vs 350.18 mg/mL for free EPS in A431 cells; *Erythrina suberosa* AgNPs had IC50 74.02 µg/mL vs 106.15 µg/mL for leaf extract and 136.73 µg/mL for AgNO3 in A-431 cells.
  • Proposed anticancer mechanisms include reactive oxygen species generation, sub-G1 arrest, up-regulation of p53 and caspase-3, inhibition of VEGF-induced activities, glutathione loss, DNA-dependent protein kinase downregulation, and Bax up-regulation with Bcl-2 downregulation.
  • Theranostic applications include fluorescent Au/Ce nanoclusters for bio-imaging in HeLa/HepG2 cells and tumor mice, biogenic AgNPs internalized by A549 and B16F10 cells, magnetically targeted drug delivery, and doxorubicin-loaded AuNPs@HMBPs for HeLa cells.

Methods

  • Narrative review, not a primary experimental study; it synthesizes literature on green synthesis of metal bionanomaterials from plants and microbes and their anticancer/theranostic applications.
  • Includes tables of phyto-sources and microbial sources for bionanoparticle synthesis and anticancer activity in various cell lines over the past 5 years, plus discussion of mechanisms, cancer diagnosis, drug delivery, and translational hurdles.
  • No systematic search strategy, inclusion criteria, or quantitative meta-analysis is reported in the text.

Limitations

  • The paper states that the exact mechanisms of metal nanoparticle biosynthesis and anticancer activity are not fully understood; residual biomolecules may remain on nanoparticle surfaces; some microbial sources include pathogenic microbes; the protein corona can compromise in vivo reliability; nanotechnology products are expensive due to manufacturing and preservation difficulties; scale-up reproducibility is challenging; and safety data are insufficient, requiring acute/chronic toxicity, pharmacokinetic, pharmacodynamic, and immune-response studies before clinical trials.
  • Evident from the text: as a narrative review, it does not provide a systematic search or quality appraisal, and many findings are cited from other studies rather than independently verified here.

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.

A language model drew the claims from the paper on 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

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.
