Remote-controlled drug release from GO-capped mesoporous silica to cancer cells by photoinduced pH-jump activation. (A) Schematic illustration of DOX@MS-BA-GOF as a drug delivery system for remote light control of drug release. (B) TEM images of amine-terminated mesoporous silica (b1), boronic acid-grafted MS (b2), and GO-capped MS-BA (b3). (C) Viability of HeLa cells after being incubated with different nanoparticles (MS-BA-GOF, MSP-BA-GOF, and DOX@MSP-BA-GOF). Cytotoxicity of DOX@MSP-BA-GOF and DOX@MSP-BA-GO incubated with HeLa cells and L02 cells for 24 h. Reprinted with permission from ref 224. Copyright 2014 American Chemical Society.
