Abstract: Devices and methods for performing separation of cell particles by dielectrophoresis in three dimensions. In one embodiment the device comprises a flow chamber having microfabricated chip with a plurality of vertical and horizontal electrodes, which may be coated with a protective layer to prevent direct contact between any electrode and a sample. The horizontal electrodes are in electrical communication with a DC or an AC power source, while the vertical electrodes are in electrical communication with an AC power source.

Abstract: Disclosed are cooling jackets for containers for beverages and other liquids. Such a jacket comprises a porous matrix as an element of the jacket body to effect the cooling of the jacket by pervaporation of a liquid contained within the jacket body. The jacket therefore cools a liquid within a container maintained in direct contact with the jacket.

Abstract: Disclosed are cooling tubes or straws for beverages and other liquids. The tubes or straws comprise a porous matrix to effect the cooling a liquid contained within by pervaporation.

Abstract: Methods for the transport and hybridization of a nucleic acid on an electrode device by providing a low conductivity buffer with a reducing agent to the device. The low conductivity buffer may also contain a zwitterion. A current and voltage is applied to a location of the device to effect electrophoretic transportation of the nucleic acid towards the location. The nucleic acid is then hybridized to a nucleic probed located at the location. The reducing agent in the low conductivity buffer may also be acting as a chaotropic agent.

Abstract: Disclosed are self-cooling containers for beverages and other liquids. Such containers comprise porous matrices as elements of the container bodies to effect the cooling of contained liquids by pervaporation. The liquid vapor can pass through the porous matrix directly to the environment or to a collector or trap comprising an absorbent material in contact with the container. Also disclosed are self-cooling containers incorporating insulative sleeves that reduce radiative warming of container surfaces yet permit sufficient pervaporative flux to cool containers residing within such sleeves.

Abstract: Disclosed are beverage containers and closures for beverage containers that are vented for the purpose of reducing negative pressure or vacuum that builds up inside the container when a beverage is being consumed therefrom. Also disclosed are closures which provide for chemical treatment of a liquid by a porous treatment matrix when the liquid is dispensed through the closure.

Abstract: Disclosed are beverage and liquid containers that use pervaporation to cool a liquid or material residing in the container. The pervaporative cooling is preferably achieved by use of porous matrices which allow for the passage through the matrix of small quantities of volatile components from a liquid or beverage, such as water or alcohol, the evaporation of which cools the container by virtue of the latent heat of evaporation of the liquid. Alternatively, a pervaporative sleeve may be used to cool a container residing within or in contact with the sleeve.

Abstract: The present invention provides improved synthetic polymer hydrogel permeation layers for use on active electronic matrix devices for biological assays. The permeation layers have a defined porous character, with mesopores in a size range between about 100 nanometers and about 1000 nanometers, and may also have micropores in the micrometer size range. The mesoporous synthetic hydrogel permeation layers demonstrate improved signal intensity and linearity characteristics as compared to nanoporous synthetic hydrogel permeation layers on active electronic matrix devices. In addition, the present invention also provides synthetic polymer hydrogel permeation layers which contain copolymerized attachment sites for nucleic acid probes or other biomolecules.
