Abstract: A method is provided for producing a microstructured molded object that is intended for culturing of biological cells. According to this method, a plastically deformable first porous film is prepared, as well as a deformable second film and a deformable sacrificial film. The first, second and sacrificial film are placed in a stack. Next, the sacrificial film is subjected to pressure to press the stack into a mold. The mold has recesses, such that deformed regions in the form of cavities are produced in the sacrificial film, the first film and the second film, and undeformed regions remain. During the pressing of the film stack into the mold, the first film and the second film are joined to each other, so that they form a composite film. At least portions of the deformed regions of the second film are etched so that sections of the second film are chemically dissolved. In these sections of the second film, sections in the deformed regions of the first film are opened up, so that the pores in these sections are again free.

Abstract: A microchip which comprises: a resinous base having a plurality of fine channels formed on one side thereof, one or more cylindrical parts disposed so as to protrude from the other side, and a through-hole which pierces each cylindrical part along the axis thereof and communicates with the fine channel so that the diameter of the inner wall of the through-hole gradually decreases from the tip end of the cylindrical part toward the fine channel at a first inclination angle; and a resinous covering member bonded to that side of the resinous base on which the fine channels have been formed. The microchip has been configured so that a liquid sample can be introduced from the tip end of each cylindrical part through the through-hole. The wall thickness of the cylindrical part on the end side where a liquid sample is to be introduced has been made smaller than the wall thickness thereof on the base side where the cylindrical part has been formed, by forming a step therebetween.

Abstract: Chemically or biochemically active agents or other species are patterned on a substrate surface by providing a micromold having a contoured surface and forming, on a substrate surface, a chemically or biochemically active agent or fluid precursor of a structure. A chemically or biochemically active agent or fluid precursor also can be transferred from indentations in an applicator to a substrate surface. The substrate surface can be planar or non-planar. Fluid precursors of polymeric structures, inorganic ceramics and salts, and the like can be used to form patterned polymeric articles, inorganic salts and ceramics, reactive ion etch masks, etc. at the surface. The articles can be formed in a pattern including a portion having a lateral dimension of less than about 1 millimeter or smaller. The indentation pattern of the applicator can be used to transfer separate, distinct chemically or biochemically active agents or fluid precursors to separate, isolated regions of a substrate surface. Waveguide arrays, combinatorial chemical or biochemical libraris, etc. can be made. Differences in refractive index of waveguide and cladding can be created by subjecting the waveguide and cladding, made of indentical prepolymeric material, to different polymerization or cross-linking conditions. Interferometers are defined by coupling arrays of waveguides, where coupling can be controlled by altering the difference in refractive index between cladding and waveguide at any desired location of the array. Alteration and refractive index can be created photochemically, chemically, or the like. Sensors also are disclosed, including biochemical sensors.

Abstract: A process is disclosed for producing metal-based, high-aspect-ratio microscale structures (HARMs), for example microchannels in a heat exchanger. The preferred manufacturing method operates in a continuous mode, and employs low-temperature rolling of metals. A process is disclosed for bonding metal microchannel sheets or plates to flat metal sheets or plates to form single-, double-, and multiple-layered microchannel structures. The process can operate at much lower temperatures than prior methods of compression microscale molding of metals, at room temperature or even lower.
