Abstract
Circulating tumor cells (CTCs) are extremely rare cells found in blood of metastatic cancer patients. There is a need for inexpensive technologies for fast enrichment of CTCs from large blood volumes. Previous data showed that antibody-conjugated lipid shell immuno-microbubbles (MBs) bind and isolate cells from biological fluids by flotation. Here, blood-stable MBs targeted to several surface markers for isolation of breast tumor cells were developed. MBs coated with anti-human EpCAM antibodies showed efficient binding of EpCAM
