摘要： The present invention relates to microfluidic devices that comprise a 3-D microfluidic network of microchannels of arbitrary complexity and to a method for fabricating such devices. In particular, the invention relates to a method of forming microfluidic devices having 3-D microfluidic networks that contain open or closed loop microchannels using a single-step molding process without the need for layer-by-layer fabrication, and to the resultant microfluidic devices. The networks of such microfluidic devices may comprise one or more microchannel circuits which may be discrete or interconnected.

摘要： A method of fabricating a nanodevice includes providing a nanowire having a first portion and a second portion. The nanowire has a polymer coating. A nanostructure is provided that is proximate to the second portion of the nanowire. Solely the first portion of the nanowire is irradiated with near-infrared radiation, thereby exciting the first portion to generate ultraviolet radiation. The generated ultraviolet radiation is guided from the first portion along the nanowire toward the second portion, so that a region of the polymer coating on the second portion is polymerized and bonds the nanostructure to the nanowire.

摘要： A cost-effective and highly reproducible method of fabricating nanowires, and small gaps or spacings in nanowires is disclosed. The nanogaps bridge an important size regime between 1 nm and 100 nm. The nanogaps can be selectively predetermined to be as small as 1.0 nm, or larger than 1000 nm. These electrode gaps can be useful in preparing molecular electronic devices that involve making electrical contact to individual molecules, such as biomolecules, or small clusters of molecules. Microelectrodes having nanogaps for electrical and magnetic applications formed by the method, and as well as biosensors and their use in detecting a biological species, such as DNA, are also disclosed.

摘要： Highly active, recoverable and recyclable transition metal-based metathesis catalysts and their organometallic complexes including dendrimeric complexes are disclosed, including a Ru complex bearing a 1,3-dimesityl-4,5-dihydroimidazol-2-ylidene and styrenyl ether ligand. The heterocyclic ligand significantly enhances the catalytic activity, and the styrenyl ether allows for the easy recovery of the Ru complex. Derivatized catalysts capable of being immobilized on substrate surfaces are also disclosed. The present catalysts can be used to catalyze ring-closing metathesis (RCM), ring-opening (ROM) and cross metatheses (CM) reactions, and promote the efficient formation of various trisubstituted olefins at ambient temperature in high yield.

摘要： The invention features a method for producing replicas of a desired structure, a master and a mold obtained from it for use in such a method. The master includes a desired structure (200) to be reproduced and an additional structure (206, 208) that assists in removal of the master from a mold, e.g. by permitting portions of the mold on opposite sides of the additional structure to flex away from one another when the master is removed from the mold. The method includes immersing the master comprising the desired structure (200) and the additional structure (206, 208) in a molding material (142), solidifying the molding material (142) to make a mold, removing the master from the mold and using the mold to produce replicas of the desired structure (200). For example, the desired structure of the master may include a loop that defines a fluid flow pathway, and the additional structure includes a membrane configured to prevent the molding material from completely passing through the loop when the mold is made from the master.
