摘要:
Methods and systems for depositing nanomaterials onto a receiving substrate and optionally for depositing those materials in a desired orientation, that comprise providing nanomaterials on a transfer substrate and contacting the nanomaterials with an adherent material disposed upon a surface or portions of a surface of a receiving substrate. Orientation is optionally provided by moving the transfer and receiving substrates relative to each other during the transfer process.
摘要:
The present invention provides a microfluidic device that includes first and second polymeric substrates. The first substrate has a higher transition temperature than the second substrate. A first substantially planar surface of the first substrate has a plurality of microscale channels disposed therein. A first substantially planar surface of the second substrate is thermally bonded to the first surface of the first substrate, neither of the first surfaces of the first and second substrates having an adhesive disposed thereon.
摘要:
Devices, systems and methods for use in separating sample materials into different sample components and then isolating one or more of the sample components for further processing or analysis are disclosed. Devices employ configurations that optionally allow a sample material to be electrophoretically separated into sample components in a separation matrix within a separation conduit. The sample components may then be detected in a detection zone in the separation conduit, and then selected components shunted to a component collection conduit within the device downstream of the detection zone for further processing or analysis based on information received at the detection zone. Methods of using these devices, and systems that incorporate these devices are also envisioned.

Reactor systems that include a reaction receptacle that includes a plurality of reservoirs disposed in the surface of a substrate. The reactor system also typically includes a temperature control element having at least a first heat exchanger thermally coupled to it. The heat exchanger is, in turn, disposed within the at least one of the reservoirs whereby the heat exchanger transfers heat to or from a fluid disposed within the reservoir, which heat is conducted to or from the temperature control element.
摘要:
The present invention provides methods of electrophoretically separating macromolecular species, as well as compositions and systems useful in carrying out such methods. Specifically, the methods of the present invention comprise providing a substrate that has at least a first capillary channel disposed therein. The surface of the channel has a first surface charge associated therewith, and is filled with a water soluble surface adsorbing polymer solution that bears a net charge that is the same as the charge on the capillary surface.
