Figure 1From: Oxaliplatin long-circulating liposomes improved therapeutic index of colorectal carcinomaCellular uptake of liposomes. The liposomes conjugated with cells after 2 h, and cellular uptake of liposomes increased over time. Cells were incubated with PI, which stained nuclei red, and Dio-labelled liposomes, which were green in colour. A considerable number of liposomes aggregated within cells at 24 h (× 400).Back to article page
