    Abstract: Provided is a method for producing a separator which has uniform and dense pores on the negative electrode surface side. A method for producing a porous polyimide film according to the present invention comprises: a first un-burned composite film forming step wherein a first un-burned composite film is formed on a substrate using a first varnish that contains (A1) a polyamide acid or a polyimide and (B1) fine particles at a volume ratio (A1):(B1) of from 19:81 to 45:65; a second un-burned composite film forming step wherein a second un-burned composite film is formed on the first unburned composite film using a second varnish that contains (A2) a polyamide acid or a polyimide and (B2) fine particles at a volume ratio (A2):(B2) of from 20:80 to 50:50 and has a lower fine particle content ratio than the first varnish; a burning step wherein an un-burned composite film composed of the first un-burned composite film and the second un-burned composite film is burned, thereby obtaining a polyimide-fine particle composite film; and a fine particle removal step wherein the fine particles are removed from the polyimide-fine particle composite film.

    Abstract: Methods and systems disclosed in the present application include membrane-like filters and methods and systems that employ these membrane-like filters to isolate circulating tumor cells and other abnormal cells from biological fluids, such as blood. The disclosed methods and systems use membrane-like filters that include a pattern or array of small, tapered apertures fabricated within a relatively thin but mechanically robust polymeric material that resists accumulation of biological-solution components and clogging during filtration of biological solutions.

    Abstract: A process for manufacturing a micromechanical structure (25) envisages: forming a buried cavity (10) within a body (1, 12) of semiconductor material, separated from a top surface (12a) of the body by a first surface layer (12); and forming an access duct (18a) for fluid communication between the buried cavity (10) and an external environment. The method envisages: forming an etching mask (14) on the top surface (12a) at a first access area (17a); forming a second surface layer (15) on the top surface (12a) and on the etching mask (14); carrying out an etch such as to remove, in a position corresponding to the first access area, a portion of the second surface layer (15), and an underlying portion of the first surface layer (12) not covered by the etching mask (14) until the buried cavity is reached, thus forming both the first access duct (18a) and a filter element (20), set between the first access duct and the same buried cavity.
