  • Patent number: 8890323
    Abstract: A nanofluidic channel fabricated in fused silica with an approximately 500 nm square cross section was used to isolate, detect and identify individual quantum dot conjugates. The channel enables the rapid detection of every fluorescent entity in solution. A laser of selected wavelength was used to excite multiple species of quantum dots and organic molecules, and the emission spectra were resolved without significant signal rejection. Quantum dots were then conjugated with organic molecules and detected to demonstrate efficient multicolor detection. PCH was used to analyze coincident detection and to characterize the degree of binding. The use of a small fluidic channel to detect quantum dots as fluorescent labels was shown to be an efficient technique for multiplexed single molecule studies. Detection of single molecule binding events has a variety of applications including high throughput immunoassays.

  • Patent number: 8834696
    Abstract: The present invention provides a device and methods of use thereof for desalting a solution. The methods, inter-alia, make use of a device comprising microchannels, which are linked to conduits, whereby induction of an electric field in the conduit results in the formation of a space charge layer within the microchannel. The space charge layer provides an energy barrier for salt ions and generates an ion depletion zone proximal to the linkage region between the microchannel and the conduit. The method thus enables the removal of salt ions from the region proximal to the conduit and their accumulation in a region distant from the conduit, within the microchannel.

  • Patent number: 8703073
    Abstract: A lithographically structured device has an actuation layer and a control layer operatively connected to the actuation layer. The actuation layer includes a stress layer and a neutral layer that is constructed of materials and with a structure such that it stores torsional energy upon being constructed. The control layer is constructed to maintain the actuation layer substantially in a first configuration in a local environmental condition and is responsive to a change in the local environmental condition such that it permits a release of stored torsional energy to cause a change in a structural configuration of the lithographically structured device to a second configuration, the control layer thereby providing a trigger mechanism. The lithographically structured device has a maximum dimension that is less than about 10 mm when it is in the second configuration.

  • Patent number: 8691180
    Abstract: A method for controlled deposition and orientation of molecular sized nanoelectromechanical systems (NEMS) on substrates is disclosed. The method comprised: forming a thin layer of polymer coating on a substrate; exposing a selected portion of the thin layer of polymer to alter a selected portion of the thin layer of polymer; forming a suspension of nanostructures in a solvent, wherein the solvent suspends the nanostructures and activates the nanostructures in the solvent for deposition; and flowing a suspension of nanostructures across the layer of polymer in a flow direction; thereby: depositing a nanostructure in the suspension of nanostructures only to the selected portion of the thin layer of polymer coating on the substrate to form a deposited nanostructure oriented in the flow direction. By selectively employing portions of the method above, complex NEMS may be built of simpler NEMSs components.

  • Patent number: 8685323
    Abstract: Methods and apparatuses for encapsulating inorganic micro- or nanostructures within polymeric microgels are described. In various embodiments, viruses are encapsulated with microgels during microgel formation. The viruses can provide a template for in situ synthesis of the inorganic structures within the microgel. The inorganic structures can be distributed substantially homogeneously throughout the microgel, or can be distributed non-uniformly within the microgel. The inventive microgel compositions can be used for a variety of applications including electronic devices, biotechnological devices, fuel cells, display devices and optical devices.

  • Patent number: 8652362
    Abstract: The present invention provides a modified curing agent for a thermosetting resin, such as epoxy resin. As one example, the epoxy curing agent comprises: (a) multiple nano graphene platelets; (b) a chemical functional group having multiple ends with a first end being bonded to a nano graphene platelet and at least a second end reactive with the epoxy resin; and (c) reactive molecules acting as a primary cross-linking agent for the epoxy resin; wherein the nano graphene platelet content is no less than 0.01% by weight based on the total weight of the modified curing agent. A modified curing agent containing reactive molecule-functionalized NGPs enable excellent dispersion of NGP in a resin matrix and the resulting nanocomposites exhibit much better properties than those of corresponding nanocomposites prepared by directly mixing dried NGPs with the thermosetting resins.
