Smart Surface-Engineered Mesoporous Silica Nanoparticles for Brain Tumor Therapy: Overcoming the Blood–Brain Barrier for Advanced Theranostics
Brain tumors, particularly glioblastoma multiforme (GBM), remain among the most lethal forms of cancer due to their aggressive nature and the formidable challenge posed by the blood–brain barrier (BBB), which restricts the delivery of therapeutic agents. Conventional treatment modalities, including surgery, radiotherap...
