Figure 3From: Quantification of the internalization patterns of superparamagnetic iron oxide nanoparticles with opposite chargeQuantification of colocalization. Manders’ coefficients M1 and M2 represent the correlation between the intracellular locations of γ-Fe2O3-PEI (green) and γ-Fe2O3-PMA (pink) with early endosomes (yellow) and lysosomes (red), respectively.Back to article page
