Fig. 7From: Dual Stimuli-Triggered Nanogels in Response to Temperature and pH Changes for Controlled Drug ReleaseFluorescent images of cytotoxicity in NIH3T3 cells with a untreated, b only β-LP, c β-LP/PNIPAM-co-AAc5, and d β-LP/PNIPAM-co-AAc20 treatment for 3 h at pH 7.4, and β-LP/PNIPAM-co-AAc20 treatment for 3 h (e) and 6 h (f) at pH 8.0. The live and dead cells are stained with calcein AM (green) and ethidium homodimer (red). Scale bars are 100 μmBack to article page
