Enzyme‐Responsive Controlled Release Using Mesoporous Silica Supports Capped with Lactose

Abstract

The great escape: A biocontrolled gated material has been prepared by grafting a lactose derivative onto the pore outlets of a mesoporous support. The galactosidase-induced hydrolysis of the β1→4 glycosidic bond in the lactose moiety (red box in picture) allows the release of a dye entrapped in the pores of the hybrid material to the bulk solution.
