Continuous-flow 3D microchannel platform captures circulating tumor cells with ~90% efficiency, enabling liquid biopsy and real-time cancer monitoring.

Calcium phosphate–capped carbon nanotubes enable pH-triggered intracellular release of doxorubicin, preventing premature drug leakage and improving targeted cancer therapy.

Self-propelled CNT microrockets rapidly capture and magnetically isolate circulating tumor cells, enabling faster liquid biopsy and early cancer detection.
