The isolation and detection of circulating tumor cells (CTCs), when these are few in number or small in mass, can enable early cancer detection . Currently, most research endeavors to isolate circulating tumor cells rely on antibodies and immunohistochemistry [2,3]. Aptamer are alternative molecules that have affinities and specificities that are comparable to those of antibodies [4,5], but these can be more readily adapted to many applications [6–9], including lab-on-a-chip devices. Here, we report use of a novel epidermal growth factor receptor (EGFR) aptamer biochip to identify and isolate cancer cells that overexpress EGFR. These results provide a solid basis for the development of diagnostic devices that can readily identify and isolate CTCs.
