  • Publication number: 20210308934
    Abstract: A method for making a nanoimprinted perovskite film or a perovskite crystal. The method includes applying a solution onto a substrate, thereby forming a precursor film or a precursor crystal, wherein the solution comprises an organo-metal halide precursor in a solvent. The method also includes fabricating an organo-metal halide perovskite film or an organo-metal halide perovskite crystal, wherein fabricating includes annealing the precursor film or the precursor crystal, thereby at least partially evaporating the solvent. The method also includes imprinting the organo-metal halide perovskite film or the organo-metal halide perovskite crystal with a mold, thereby forming an imprinted film or an imprinted crystal. The method also includes separating the mold from the imprinted film or the imprinted crystal, thereby forming the perovskite film or the perovskite crystal.

  • Publication number: 20130089932
    Abstract: The present invention provides a device and methods for the detection and quantification melamine in a sample by rapid and specific electrochemical detection. The present invention includes using a field-effect transistor (FET) biosensor having an open Si channel with a melamine antigen, or hapten, or an antibody, anchored via a linker molecule such as self assembled monolayer to the surface of the gate dielectric of the said open Si channel. The anchoring molecule having the capability of detecting melamine directly or indirectly by selectively binding melamine antibodies, which changes a field-effect on a Si channel, causing a change in conductivity of the FET. This change in conductivity can be measured and is used to determine the presence or absence of melamine in a sample compared to a standard signal or pre-measured database.

  • Publication number: 20090196826
    Abstract: The present invention includes compositions, methods and pharmaceutical compositions formed by template-directed polymer molding by contacting a porous template with one or more layers of polymeric material coated on a release layer coated on a substrate, applying pressure to the porous template, the substrates or both and separating the porous template from the polymer material to form one or more polymer nonspherical nanostructures with one or more layers on the substrate. The template includes one or more nonspherical nanostructure features. The size and shape of the one or more single- or multi-layer polymeric nonspherical nanostructures are controlled by the one or more nonspherical nanostructure features and the polymer material optionally including one or more active agents with or without retardants, dyes, etc.
