Learning to let go with age: Intracellular controlled release of molecules within senescent cells was achieved using mesoporous silica nanoparticles (MSNs) capped with a galacto-oligosaccharide (GOS) to contain the cargo molecules (magenta spheres; see scheme). The GOS is a substrate of the senescent biomarker, senescence-associated β-galactosidase (SA-β-gal), and releases the cargo upon entry into SA-β-gal expressing cells.
使用被半乳糖低聚糖（GOS）覆盖的介孔硅纳米粒子（MSNs）来实现衰老细胞内分子的细胞内控制释放，以包含货物分子（品红色球体；见方案）。GOS 是衰老生物标志物，衰老相关β-半乳糖苷酶（SA-β-gal）的底物，并且在进入表达 SA-β-gal 的细胞时释放货物。
