(B) Schematic of molecularly imprinted polymer coated CDs for cancer cell targeting bioimaging, (C) Confocal microscope images of fixed HaCaT and HeLa cells treated with CDs, CD-NIP, and CD-MIPGlcA. (D) Confocal micrographs showing labeling of GlcA on a single HeLa cell by CD-MIPGlcA (green) and nuclear staining with PI (red). (E) Analysis of labeled cells with CD-MIPGlcA, CDNIP, and CD as obtained from Image J by measuring the normalized fluorescence of each single cell area from five different images.
