    摘要: This invention is predicated on the present applicants' discovery that nanostructures comprising discrete regions of different composition can be used to deliver to a biological cell a desired combination of molecules in close proximity. Different molecules can be selectively bonded to discrete regions of different composition in sufficiently close physical relationship to enhance delivery or effectiveness within the cell. The preferred nanostructures are multicomponent nanorods. Important applications include delivery of missing DNA sequences for gene therapy and delivery of antigens or DNA encoding antigens for vaccination.

    摘要: Methods for the identification of microorganisms or infectious disorders are disclosed, comprising obtaining a suitable sample from sources such as persons, animals, plants, food, water or soil. The methods also comprise providing tailored nucleic acid substrate(s) designed to react with a type 1 topoisomerase from one or more microorganism(s) or infectious agent(s), and incubating said substrate with said sample, or extracts or preparations from the sample, so that the substrate is processed by said topoisomerase if said microorganism(s) or infectious agent(s) is present in the sample. Microfluidic-implemented methods of detecting an enzyme, in particular a DNA-modifying enzyme, are also provided, as well as methods for detecting a cell, or a microorganism expressing said enzyme. The enzyme is detected by providing a nucleic acid substrate, which is specifically targeted by that enzyme.
