Figure 3.

Interaction of quercetin nanomicelles with Caco-2 cells. (Panel A)Cellular accumulation of FITC-labeled nanomicelles over 24 hours of incubation at 37°C Representative images from fluoresence confocal microscopy are shown. (Panel B) Change in TEER upon treatment with quercetin in free (green) and nanomicellar (orange) forms, as well as empty nanomicelles (blue) and 1% triton-X (red), with the arrow indicating treatment duration of 24 hours.

Notes: ⁺, ^#, *, and ^‡ represent P < 0.05 compared to values at t = 0 hours.
