The authors also thank the Generalitat Valencia (Project PROMETEO/2018/024) for support.The construction of a novel enzyme-controlled nanomachine with multiple release mechanisms for oncommand delivery is described. This nanodevice was assembled by modifying mesoporous silica nanoparticles with 2-(benzo[d]thiazol-2-yl)phenyl 4-aminobenzoate moieties, and further capped with b-cyclodextrin-modified glucose oxidase neoglycoenzyme. The device released the encapsulated payload in the presence of H2O2 and acidic media. The use of glucose as an input chemical signal also triggered cargo release through the enzymatic production of gluconic acid and hydrogen peroxide, and the subsequent disruption of the gating mechanism at the mesoporous surface. The nanodevice was successfully employed for the enzyme-controlled release of doxorubicin in HeLa cancer cells.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article2050-750Xhttps://doi.org/10.1039/d2tb01069krestricted access543Química analítica (Química)2301 Química Analítica
