Gradient Technology for High-Throughput Screening of Interactions between Cells and Nanostructured Materials
Figure 3
Fluorescence micrographs of Hoechst 33342 stained MG63 osteoblast-like cells on plasma polymer chemical gradients of carboxylic acid deposited onto (a) a flat silicon wafer and (b) a porous silicon wafer. Images were recorded after 4 h of incubation with 7.7 × 104 cells/mL. Scale bar = 500 μm.
