Abstract:
Engineered reaction containers that can be physically and chemically defined to control the flux of molecules of different sizes and charge are disclosed. Methods for constructing small volume reaction containers through a combination of etching and deposition are also disclosed. The methods allow for the fabrication of multiple devices that possess features on multiple length scales, specifically small volume containers with controlled porosity on the nanoscale.

Magnetic tweezers have two jaws formed by thin magnetic films connected together via a hinge. The magnetic tweezers include a nanoparticle formed by a stack of thin magnetic films. A process for fabricating the magnetic tweezers by techniques used in the fabrication of microelectronic components is presented.
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:
An apparatus includes a substrate having a top surface, a substantially regular array of raised structures located over the top surface, and a layer located on the top surface between the structures. Distal surfaces of the structures are farther from the top surface than remaining portions of the structures. The layer is able to contract such that the distal surfaces of the structures protrude through the layer. The layer is able to swell such that the distal surfaces of the structures are closer to the top surface of the substrate than one surface of the layer.
Abstract:
A microparticle includes an oblong flexible tail able to propel the microparticle in a solution along a trajectory using beats transverse to the trajectory, the tail including at least one magnetic element such that the magnetic element causes beats of the tail under the action of an external alternating magnetic field non-collinear with the trajectory and a head mechanically connected to a proximal end of the tail. The microparticle includes at least one layer of material formed from one piece and including the tail and the head, the dimensions and/or shape of the head being selected such that the beats of the proximal end of the tail are limited with respect to the beats of the distal end of the tail and such that the head does not perform a complete revolution around an axis parallel to the trajectory under the effect of the external alternating magnetic field.

Abstract:
A process for producing a fluorocarbon microstructure capable of easily fabricating a three-dimensional fluorocarbon microstructure. The process for producing a fluorocarbon microstructure comprises a first processing step for forming, on a substrate (2), a film deposition portion with a given pattern made up of a through-hole figure by etching the substrate (2), a fabricating step for forming a fluorocarbon film (6) on an inner circumferential surface of a film deposition portion (9) to fabricate a fluorocarbon region surrounded by the fluorocarbon film (6), and a second processing step for fabricating the fluorocarbon microstructure protruding from a processing surface of the substrate (2) by etching a given region other than a fluorocarbon region on the substrate (2). Hence, the three-dimensional fluorocarbon microstructure can be fabricated which comprises a complicated structure that has conventionally been hard to fabricate. Thus, a microchannel (1) equipped with the three-dimensional fluorocarbon microstructure can be easily fabricated.
