Peptide tag-induced HRP-mediated preparation of a streptavidin-immobilized redox-sensitive hydrogel. a Schematic illustration of HRP-mediated preparation of a streptavidin-immobilized redox-sensitive hydrogel and intracellular delivery. b Cytotoxicity assay of DLD1 cells incubated with C-SA-Y nanogel functionalized with CPP and saporin. The viability of cells without any treatment was set as 100%. Cells without any treatment (1) and treated with C-SA-Y nanogel (2), C-SA-Y nanogel with CPP (3), C-SA-Y nanogel with saporin (4), C-SA-Y nanogel with CPP and saporin (5), and saporin (6)
