Researchers have designed a multifunctional nanoplatform that loads the chemotherapy drug docetaxel onto iron copper sulfide nanoparticles and combines three treatment modes—chemotherapy, chemodynamic therapy and photothermal therapy—in a single leukemia-targeted system, according to a study published in the Journal of Nanoparticle Research.
The platform, described in the paper as DT/FCS@APTS-mPEG-HA, is built on FeCuS2 nanoparticles that serve as a drug carrier. The researchers modified the particle surface with 3-aminopropyltriethoxysilane (APTS) and with methoxy polyethylene glycol (mPEG)-functionalized hyaluronic acid, and then incorporated docetaxel to produce the final nanoparticles.
According to the abstract, the nanoplatform demonstrated superior photothermal efficacy under exposure to a 980-nanometer near-infrared laser.
The nanoparticles also proficiently produced toxic hydroxyl radicals through Fenton and Fenton-like reactions, the authors report. The paper states that this radical generation augmented the reactive oxygen species-facilitated treatment efficacy, adding a chemodynamic component to the platform.
Drug release from the nanoparticles was triggered by both near-infrared light and glutathione, according to the study. The authors report that this NIR- and GSH-triggered release facilitated rapid, controlled delivery of docetaxel to the tumor site, an approach intended to concentrate the chemotherapy payload where it is needed.
The motivation behind the design, as described in the paper, is the limitation of traditional chemotherapy in leukemia treatment. The authors note that drug resistance and severe side effects heavily limit clinical outcomes, and they identify ferroptosis—an iron-dependent, non-apoptotic form of regulated cell death characterized by lipid peroxide accumulation—as a promising strategy to eradicate resistant leukemia cells.
By integrating chemotherapy, chemodynamic therapy and photothermal therapy in one nanoparticle, the platform is intended to overcome the limitations of monotherapy, enhance systemic stability and facilitate leukemia cancer therapy, the authors write. The combination of iron-dependent chemistry with photothermal heating is presented as a route to amplify ferroptosis in leukemia cells.
The study is published in Volume 28 of the Journal of Nanoparticle Research, with the article dated 28 October 2026. The reported findings describe the design, production and in vitro performance of the nanoplatform as characterized in the paper; the abstract describes the platform’s capabilities and treatment mechanisms rather than clinical outcomes, and further evaluation would be needed to establish any benefit in patients.
