A circulating tumor cell (CTC) is a cancer cell from a primary tumor that has shed into the blood of the circulatory system, or the lymph of the lymphatic system. [1] CTCs are carried around the body to other organs where they may leave the circulation and become the seeds for the subsequent growth of secondary tumors .
One example involves a biochips to better detect and diagnose cancer. These microfluidic chips are among the world's first in being able to isolate circulating tumor cells from patient's blood. This patented technology is simple and easy to use, providing a next generation of non-invasive 'liquid biopsy' devices for cancer diagnosis. [19]
He has been working on developing microfluidic devices, which are small, chip-like devices used for medical and scientific purposes. Instead of using antibodies to capture circulating tumor cells (CTCs), which are cancer cells found in the blood, he uses special DNA or RNA sequences called aptamers.
This parameter is critical in determining cell health and response to experimental or therapeutic settings. Viability of the cells in flow cytometry should be around 95% but not less than 90%. [42] Circulating tumor cells: Flow cytometry is essential for isolating and purifying circulating tumor cells (CTCs) from blood samples.

Two areas in particular that are receiving attention as surrogate markers include circulating tumor cells (CTCs) [45] [46] and circulating miRNAs. [47] [48] Both these markers are associated with the number of tumor cells present in the blood, and as such, are hoped to provide a surrogate for tumor progression and metastasis. However ...
