Here, we first systematically review the primary strategies for deploying nanoparticles in the brain, with a particular focus on minimally invasive and precise deployment approaches that leverage external physical field interventions to overcome the blood-brain barrier. Next, we critically summarize the key physical factors governing nanoparticle transport across the blood-brain barrier.

To address this limitation, we introduced defects into STA-16(Co) by selectively removing linkers through treatment with nitrilotriacetic acid, significantly improving water diffusion kinetics. The defective MOFs demonstrate markedly faster water saturation rates─delivering ∼50% more water in a 40 min cycle─while maintaining the same uptake capacity and isothermal behavior as pristine STA-16(Co).
