Advanced nanomicelles for targeted glioblastoma multiforme therapy.

Glioblastoma multiforme (GBM) is the most aggressive and malignant primary brain tumor, classified as grade IV by the WHO. Despite standard treatments like surgical resection, radiotherapy and chemotherapy (i.e. temozolomide), GBM's prognosis remains poor due to its heterogeneity, recurrence and the impermeability of the blood-brain barrier (BBB). The exact cause of GBM is unclear with potential factors including genetic predisposition and ionizing radiation. Innovative approaches such as nanomicelles-nanoscale, self-assembled structures made from lipids and amphiphilic polymers show promise for GBM therapy. These nanocarriers enhance drug solubility and stability, enabling targeted delivery of therapeutic agents across the BBB. This review explores the synthesis strategies, characterization and applications of nanomicelles in GBM treatment. Nanomicelles improve the delivery of both hydrophobic and hydrophilic drugs and provide non-invasive delivery options. By offering site-specific targeting, biocompatibility, and stability, nanomicelles can potentially overcome the limitations of current GBM therapies. This review highlights recent advancements in the use of nanomicelles for delivering therapeutic agents and nucleic acids addressing the critical need for advanced treatments to improve GBM patient outcomes.
