Surface immobilized sgc8 aptamer selectively captures target cells. Stepwise aptamer immobilization scheme (A). Representative images of cells captured on sgc8 aptamer immobilized surface with target cells at 212 cell/mm2 (B) and control cells at 2 cell/mm2 (C). Representative images of cells captured on random DNA immobilized surface with target cells at 7 cell/mm2 (D) and control cells at 4 cell/mm2 (E). Bar = 500 µm.
