Fig. 4From: Distribution of PLGA-modified nanoparticles in 3D cell culture models of hypo-vascularized tumor tissueNP distribution profiles quantifying the mean fluorescence intensity (MFI) vs. penetration distance through liquid overlay (LO) spheroids. Distribution profiles are shown as a function of NP treatment and tumor cell type. Average of the values along distance is denoted by the dark linesBack to article page
