Glioblastoma multiforme (GBM) is
a highly malignant brain tumor
with a poor prognosis and limited treatment options. Drug delivery
by stimuli-responsive nanocarriers holds great promise for improving
the treatment modalities of GBM. At the beginning of the review, we
highlighted the stimuli-active polymeric nanocarriers carrying therapies
that potentially boost anti-GBM responses by employing endogenous
(pH, redox, hypoxia, enzyme) or exogenous stimuli (light, ultrasonic,
magnetic, temperature, radiation) as triggers for controlled drug
release mainly via hydrophobic/hydrophilic transition, degradability,
ionizability, etc. Modifying these nanocarriers with target ligands
further enhanced their capacity to traverse the blood–brain
barrier (BBB) and preferentially accumulate in glioma cells. These
unique features potentially lead to more effective brain cancer treatment
with minimal adverse reactions and superior therapeutic outcomes.
Finally, the review summarizes the existing difficulties and future
prospects in stimuli-responsive nanocarriers for treating GBM. Overall,
this review offers theoretical guidelines for developing intelligent
and versatile stimuli-responsive nanocarriers to facilitate precise
drug delivery and treatment of GBM in clinical settings.
