photoswitchableimaging of intracellular glutathione (GSH). The photochromic glycosheet manifests significantly turn-on fluorescence and dynamic ON/OFF fluorescence signals in response to GSH, which makes it favorable for intracellular GSH double-check in targeted human hepatoma cell line (HepG2) through the
therapy.

Cells are the basic structure and functional unit of biological organisms. Human diseases and aging are closely related to the states of cells. Thorough
design and further broaden the availability of photoswitchable biosensing, herein we report a glycosheet hybrid sensor (Glyco-DTE@MnO2) fabricated by 2D MnO2 nanosheets and dithienylethene fluorescence reporter (Glyco-DTE) to achieve cell-targeted photoswitchableimaging of intracellular GSH.
