Green synthesis of metal nanocarriers: A perspective for targeting glioblastoma.

Glioblastoma, the most aggressive brain cancer, is challenging to treat owing to the difficulty of crossing the blood-brain barrier, high recurrence rates and significant mortality. This review highlights the potential of green synthesis methods in developing metal nanoparticles (MNPs) as a sustainable solution for drug delivery systems targeting glioblastoma. We explore the unique properties and modes of action of MNPs synthesised through eco-friendly processes by focusing on their bioavailability and precision in brain targeting, and discuss the potential of MNPs to target glioblastoma at the molecular level. Integrating green synthesis into cancer therapeutics represents a novel paradigm shift towards treatments with higher efficacy and lower environmental impact, offering hope in the fight against glioblastoma.
