Surface-immobilized aptamers for cancer cell isolation and microscopic cytology.

Abstract excerpt

Exposing rare but highly malignant tumor cells that migrate from the primary tumor mass into adjacent tissue(s) or circulate in the bloodstream is critical for early detection and effective intervention(s). Here, we report on an aptamer-based strategy directed against epidermal growth factor receptor (EGFR), the most common oncogene in glioblastoma (GBM), to detect these deadly tumor cells. GBMs are characterized...
