    Fineline Imaging microfluidic channel masks
    (A) Representative confocal images of MDCK II monolayers expressing CaaX-GFP to label cell membrane (green), stained with Hoechst 33342 to label cell nucleus (cyan), and pre-incubated with 20 µg/mL red fluorescent NPs (red) for 24 hours. Panel on the right is a z -stack image. (B) Cell-associated NP fluorescence of different cell lines quantified using flow cytometry. The median fluorescence intensity (MFI) of N = 3 biological replicates is plotted in the log scale. (C) A method to quantify the mass of NPs using epifluorescence microscopy and <t>microfluidic</t> devices. 20 to 1600 µg/mL of NPs were injected into a microfluidic channel with known height similar to tissue cells, and imaged using an epifluorescence microscope. The total fluorescence per unit area is a linear function of the NP density. n = 3 technical repeats per condition. (D) Quantification of cell-associated NP density at different NP loading times in the MDCK II monolayer. 20 µg/mL NPs were loaded for 1, 6, and 24 hours, followed by washing and epifluorescence imaging. The mass density was then calculated based on the cell height measured in (A) and the calibration curve in (C). N = 4. (E) The relative NP release at different times after 24 hours of NP loading in the MDCK II monolayer. The release fraction is the loss of fluorescence intensity compared to the intensity measured immediately after NP loading by tracking the same region of cells. N = 4. (F) Schematic of the in vivo model. C57BL/6 mice were administered 100 µL of NPs (2 mg/mL) via intravenous (i.v.) injection, then sacrificed at 1, 7, and 30 days post-injection. NP retention was assessed by IVIS imaging. (G) NP distribution in major organs and brain 30 days post-injection. (H) Representative images and total radiant efficiency of NPs in liver at 1, 7, and 30 days post-injection. (B, C, D, E, H) Error bars represent standard deviation. Student’s t -test or one-way ANOVA was used. Representative statistical significance is shown: ns for p > 0.05, * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001. (A) Scale bar = 10 µm.

NPs in the lower compartment were quantified using microfluidic devices. Empty transwells were used as baseline controls. N = 5. (G) Quantification of trans-epithelial NP transport in the presence of Dynasore or LY294002 using the assay in (F). N = 4-5. (H) Schematic illustration of pathways affecting NP-cell association.
