Abstract

Nanomaterial-based brain-targeted delivery systems may enhance therapeutic efficacy for glioblastoma treatment.

Glioblastoma is associated with high morbidity and mortality due to challenges like the blood-brain barrier and blood-brain tumor barrier.
Conventional drugs often face limitations such as poor penetration of the brain barrier, short half-lives, and low bioavailability.
Innovative nanoparticle-mediated strategies are explored for improving drug transport kinetics in glioblastoma treatment.
Biomimetic nanoparticles offer unique advantages that could facilitate more effective delivery of therapeutic agents.
Current challenges and future research directions in this field may lead to better maximization of therapeutic effects for gene drugs or chemotherapeutic agents.

Glioblastoma (GBM) poses a formidable challenge because of its high morbidity and mortality. The therapeutic efficacy of GBM is significantly hampered by the intricate blood-brain barrier (BBB) and blood-brain tumor barrier (BBTB). Nanomaterial-based brain-targeted delivery systems have shown great potential for effectively delivering therapeutic agents for GBM treatment by overcoming the limitations of conventional drugs, such as poor BBB penetration, a short half-life, and low bioavailability. This review focuses on an in-depth analysis of the interplay between the BBB/BBTB and drug transport kinetics while analyzing innovative nanoparticle-mediated strategies for enhanced GBM treatment. Moreover, the delivery strategies of nanoparticle-based brain-targeted systems are emphasized, with particular attention given to biomimetic nanoparticles (BMNPs), whose unique advantages. The current challenges, translational potential, and future research directions in this rapidly evolving field are comprehensively discussed, highlighting advances in nanomaterial applications. This review aims to stimulate further research into GBM delivery systems, offering promising avenues for maximizing the therapeutic effects of gene drugs or chemotherapeutic agents in practical applications.
