Abstract: More than 90% of cancer deaths result from metastasis, hence understanding of metastasis and detection of cancer before spreading are extremely important. During metastasis, some cancer cells escape from the primary tumor and enter the bloodstream, becoming circulating tumor cells (CTCs). As a result, CTCs are potential biomarkers for cancer diagnosis and prognosis. However, CTCs are extremely rare in the bloodstream, making their detection very challenging. To address this, we have developed several microfluidic devices for CTC Isolation and applied the platform to blood samples of metastatic pancreatic cancer patients. Biological protein synthesis is often required for studying a gene’s function since the corresponding protein is needed to characterize its biological properties. Protein synthesis is primarily implemented using over-expression in E. coli cells, but cell-based methods can be cost-prohibitive to carry out in a high-throughput format. We have developed miniaturized fluid array devices for high-throughput cell-free protein synthesis; up to 96 proteins can be simultaneously produced. Due to integrated elements that enable nutrient replenishment and byproduct removal, synthesis yield in our
