    摘要: Thin parylene C membranes having smooth front sides and ultrathin regions (e.g., 0.01 μm to 5 μm thick) interspersed with thicker regions are disclosed. The back sides of the membranes can be rough compared with the smooth front sides. The membranes can be used in vitro to grow monolayers of cells in a laboratory or in vivo as surgically implantable growth layers, such as to replace the Bruch's membrane in the eye. The thin regions of parylene are semipermeable to allow for proteins in serum to pass through, and the thick regions give mechanical support for handling by a surgeon. The smooth front side allows for monolayer cell growth, and the rough back side helps prevents cells from attaching there.

    摘要: The present invention provides methods for designing a filtration systems for capturing viable tumor cells, such as circulating tumor cells at high efficiency and high viability. The methods involve development of a set of “key engineering design parameters” that are crucial to achieve high tumor cell viability. These important design parameters include the filter geometry design, fluid delivery method, transfilter pressure and total filtration time.

    摘要: The present invention provides a method for diagnosing cancer, predicting a disease outcome or response to therapy in a patient sample. The method involves isolating a circulating tumor cell (CTC), for example, a viable CTC, from a sample using a parylene microfilter device comprising a membrane filter having or consisting of a parylene substrate, which has an array of holes with a predetermined shape and size; and detecting and quantifying telomerase activity in blood circulating tumor cells. The invention further provides methods of using cells live-captured in various applications.
