(a) Left: Immobilization of DNA-conjugated MCF-7 cells onto a glass surface with a microarray of a complementary DNA sequence. The neighboring areas on the glass surface having a non-complementary DNA sequence is left untouched. Right: selective immobilization of Jurkat (green) and MDA-MB-231 cells (blue) by DNA hybridization [56]. (b) Schematic of DMAP-tethered antibody labeling of cell surface receptors [60]. (c) Fluorescence images of EGFR expressive human epidermal carcinoma A431 cells labeled by DMAP-tethered anti EGFR affibody conjugated to fluorescein dye, compared to cells (−) affibody-DMAP and cells reacted with non-affibody conjugated PEG-DMAP [60].
