Antibody-functionalized microengine rockets can selectively capture and transport pancreatic cancer cells in complex biological media. In their Communication on page 4161 ff., Zhang, Wang, and co-workers report that these microrockets recognize individual cancer cells from a cell mixture with high selectivity. This strategy holds promise for the design of bioanalytical protocols and microchip devices for early-stage tumor cell detection.
