(a) Microrockets for capture and isolation of CTCs. The anti-CEA mAb-modified microrockets recognize the CEA surface antigens on the target CTCs, allowing selective pickup and transport. (b, c) Pickup and transport in PBS and diluted serum. Time-lapse images demonstrate the pickup and transport of a CEA+ pancreatic cancer cell by an anti-CEA mAb-modified microrocket in PBS (b) and human serum (c) at intervals of 2 and 1 s, respectively.
