Cell imaging results. AFM height/phase images of nanoscale Per NS (a), Per/OFN NP (d), Cor NR (g), and Cor/OFN NR (j). Confocal images of MCF-7 cells and labeled by Per NS (c), Per/OFN NP (f), Cor NR (i), and Cor/OFN NR (l), as well as the corresponding controls unlabeled by any samples (b, e, h, k). All the insets are the results under bright field. λex = 405 nm. Scale bars in a, d, g, j are 200 nm. Scale bars in b, c, e, f, h, i, k, l are 75 μm
