    摘要: Methods and apparatus are provided for assaying cell samples, which may be living cells, using probes labeled with composite organic-inorganic nanoparticles (COINs) and microspheres with COINs embedded within a polymer matrix to which the probe moiety is attached. COINs intrinsically produce SERS signals upon laser irradiation, making COIN-labeled probes particularly suitable in a variety of methods for assaying cells, including biological molecules that may be contained on or within cells, most of which are not inherently Raman-active. The invention provides variations of the sandwich immunoassay employing both specific and degenerate binding, methods for reverse phase assay of tissue samples and cell microstructures, in solution displacement and competition assays, and the like. Systems and chips useful for practicing the invention assays are also provided.

    摘要: Embodiments of the present invention provide methods for coating nanoparticles with polymeric coatings and nanoparticles that are coated with polymeric coatings. The polymeric coatings typically comprise two or more layers wherein the first layer has a charge that is opposite to that of the second layer. In further embodiments, the nanoparticles that can act as labels or reporters are coated with polymeric coatings. Optionally, these reporter or label nanoparticles may be Raman-active, such that they provide a distinctive Raman signature upon excitation with electromagnetic radiation.

    摘要: The present disclosure concerns methods for producing and/or using molecular barcodes. In certain embodiments of the invention, the barcodes comprise polymer backbones that may contain one or more branch structures. Tags may be attached to the backbone and/or branch structures. The barcode may also comprise a probe that can bind to a target, such as proteins, nucleic acids and other biomolecules or aggregates. Different barcodes may be distinguished by the type and location of the tags. In other embodiments, barcodes may be produced by hybridization of one or more tagged oligonucleotides to a template, comprising a container section and a probe section. The tagged oligonucleotides may be designed as modular code sections, to form different barcodes specific for different targets. In alternative embodiments, barcodes may be prepared by polymerization of monomeric units. Bound barcodes may be detected by various imaging modalities, such as, surface plasmon resonance, fluorescent or Raman spectroscopy.

    摘要: Method and device to collect multiplex data simultaneously in analyte detection and analyze the data by experimentally trained software (machine-learning) is disclosed. Various ways (magnetic particles and microcoils) are disclosed to collect multiple reporter (tag) signals. Multiplex detection can increase the biomolecule analysis efficiency by using small sample size and saving assay reagents and time. Machine learning and data analysis schemes are also disclosed. Multiple affinity binding partners, each labeled by a unique reporter, are contacted with a sample and a green spectrum is taken to detect multiple reporter signals. The spectrum is deconvoluted by experimentally trained software to identify multiple analytes.

    摘要: Modified and functionalized metallic nanoclusters capable of providing an enhanced Raman signal from an organic Raman-active molecule incorporated therein are provided. For example, modifications include coatings and layers, such as adsorption layers, metal coatings, silica coatings, and organic layers. The nanoclusters are generally referred to as COINs (composite organic inorganic nanoparticles) and are capable of acting as sensitive reporters for analyte detection. A metal that enhances the Raman signal from the organic Raman-active compound is inherent in the nanocluster. A variety of organic Raman-active compounds and mixtures of compounds can be incorporated into the nanocluster.
