• [29]. Other microscopy techniques that are useful for such studies are correlative light and electron microscopy (CLEM) [30], confocal microscopy with Z-stacks [4], and structured illumination microscopy (SIM) which can also demonstrate in which organelles the NPs are localized. The SIM image shown in

• -NP uptake was further examined by 3D-structured illumination microscopy and quantified with high-content analysis. Briefly, rBCEC4 cells were seeded at 36,000 cells (96-well plate) or 180,000 cells (24 well plate), left to adhere, then exposed to either PCL-, PLLA- or Au-NPs for either 30 min, 2 h or
