Fig. 5From: Preferential drug delivery to tumor cells than normal cells using a tunable niosome–chitosan double package nanodelivery system: a novel in vitro modelAccumulation of chitosan around tumor cells following their incubation with paclitaxel–BODIPY 564/570–chitosan–niosome complex. Cells were treated for 20 min to 1 h with chitosan/paclitaxel (0.4 µM) conjugated to red–orange fluorescent BODIPY 564/570. Scale bar = 10 µmBack to article page
