Abstract

Here we describe the construction of an integrated and pH-sensitive nanomachine with layer-by-layer supramolecular design and enzymatic control for on-command delivery. The nanodevice comprises a first layer of β-cyclodextrin-coated gold nanoparticles as capping element of benzimidazole functionalized mesoporous silica nanoparticles, and a second control layer based on an adatamantane-modified glucose oxidase derivative. The nanomachine was selectively fuelled by glucose and successfully employed for the autonomous release of doxorubicin in HeLa cancer cells.
