摘要： Methods and apparatuses for generating electrically-conductive and/or semi-conductive films, and more specifically, methods and apparatuses for generating conductive and/or semi-conductive films having nanoscale features are provided. In one embodiment, an electrically-conductive or semi-conductive film (e.g., a gold layer of less than 50 nanometer thickness) is provided on a substrate (e.g., a poly(dimethylsiloxane) (PDMS) stamp). The substrate may optionally include patterns or features having raised and recessed portions. A first portion of the film may be removed from the substrate, e.g., by methods such as physically contacting the first portion of the film with a surface to which the first portion preferentially adheres. This process can leave a second portion of the film remaining on the substrate. In some embodiments, the second portion includes at least one region having a dimension substantially parallel to a portion of the substrate i.e., of less than 50 nanometers. The second portion of the film may be used to establish electrical communication with an electrical contact. Advantageously, electrically-conductive and/or semi-conductive films having nanoscale features can be fabricated over large areas (e.g., areas greater than 1 cm2) in a single step.

摘要： Self-regulating pressure source. The pressure source includes a chamber enclosing a chemical monopropellant. A moveable boss is attached to a deformable membrane sealing an air chamber, the moveable boss and air chamber being disposed within the chamber. A catalyst is disposed around the membrane so as to be covered by the boss in a retracted position so that the monopropellant is broken down by the catalyst to produce a gas. The gas pressure will increase within the chamber causing air in the air chamber to compress thereby to pull the boss into the retracted position to cover the catalyst thereby to regulate the pressure within the chamber. The self-regulating pressure source is particularly suited to power fluidic elastomeric actuators.

摘要： A microfluidic valve assembly includes a structure defining a microfluidic fluid path and an actuator that can be moved between different positions controlling flow through the channel. In one embodiment, the actuator can be threaded into at least a portion of the structure, and can be moved rotationally between a first position, causing relatively greater constriction of a microfluidic fluid path, and a second position causing relatively lesser constriction of the fluid path. Actuating the actuator, e.g., by rotation, can deform material between the valve and the fluid path, thereby constricting at least a portion of the underlying fluid path and regulating the flow of a fluid in the fluid path. In another aspect, the invention provides a reservoir into which fluid can be placed and from which fluid can be introduced into a microfluidic system. In one embodiment, the reservoir is expandable and thereby able to store fluid under pressure for delivery to a microfluidic system.

摘要： The present invention provides a series of methods, compositions, and articles for altering a property of a surface (for example, the cytophilicity and/or the hydrophilicity), by exposing at least a portion of the surface to a non-chemical, force-creating field and/or force, such as an electric field. The field/force may be created by any suitable technique. For instance, the field can be created by applying a voltage across the surface, by electrical induction, etc. In certain embodiments, the surface includes molecules attached thereto that can be detached when exposed to non-chemical, force-creating fields and/or forces, thereby altering the chemical composition of at least a portion of the surface. In one set of embodiments, the molecules attached to the surface may include molecules forming a self-assembled monolayer on the surface. In some embodiments, the molecules attached to the surface may include thiol moieties (e.g., as in an alkanethiol), by which the molecule can become attached to the surface. In certain cases, the molecules may be terminated at the unattached end with one or more hydrophilic groups, for example, unmodified ethylene glycol moieties. In some cases, the molecules attached to the surface may include one or more moieties that can bind to various entities such as proteins, peptides, nucleic acids, drugs, cells, etc. In certain embodiments, the techniques are used to enable novel assays for cell motility and/or spreading and screening tests for determining drugs and/or treatments effective in increasing or decreasing cell shape changes and/or motility on surfaces.
