Abstract Extracellular vesicles (EVs) are emerging as a potential diagnostic test for cancer. Owing to the recent advances in microfluidics, on‐chip EV isolation is showing promise with respect improved recovery rates, smaller necessary sample volumes, and shorter processing times than ultracentrifugation. Immunoaffinity‐based microfluidic using anti‐CD63 widely used; however, not specific cancer‐EVs, some cancers secrete EVs low expression of CD63. Alternatively, phosphatidylserine (PS),...

As the recognition between natural killer (NK) cells and cancer does not require antigen presentation, NK are being actively studied for use in adoptive cell therapies rapidly evolving armamentarium of immunotherapy. In addition to utilizing cells, recent studies have shown that exosomes derived from also exhibit antitumor properties. Furthermore, these cell-derived higher stability, greater modification potentials less immunogenicity compared cells. Therefore, technologies allow highly...

Circulating tumor cells (CTCs) are extremely rare shed from tumors into the blood stream. These can provide valuable information about their of origin and direct treatment decisions to improve patient outcomes. Current technologies isolate CTCs a limited volume often require pre-processing that leads CTC loss, making it difficult enough perform in-depth analysis. Many inertial microfluidic devices have been developed at high flow rates, but they typically either dilution, remove red cells,...
