Cell-Mimetic Antifouling Poly(ethylene glycol) Interface Enables Selective Capture and Viable Release of Circulating Tumor Cells
Lab platform selectively isolates tumor cells from blood with minimal contamination, advancing liquid biopsy technology.
A cell-mimetic PEG-functionalized silica substrate armed with bispecific antibodies (anti-PEG/anti-HER2) selectively captured HER2-overexpressing tumor cells (SKBR3) with reduced nonspecific immune cell adhesion, and enabled glutathione-triggered viable release for downstream culture/analysis. The platform demonstrates a laboratory CTC isolation approach for liquid biopsy applications.
