    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: The present methods, compositions and systems are concerned with biomolecule 130 detection, identification and/or quantification by rolling circle amplification (RCA) and Raman detection. In particular embodiments of the invention, the RCA is exponential RCA or linear RCA. In some embodiments of the invention, the Raman detection is SERS or SERRS. The circular DNA template 150, 210, 310 to be amplified may comprise one or more polythymidine 320 residues, resulting in amplification products 170, 230, 250, 330, 410 containing multiple polyadenylate 340, 420 residues. The polyadenylates 340, 420 may be directly detected by Raman detection. Alternatively, one or more Raman labels may be incorporated into the amplification products 170, 230, 250, 330, 410 to facilitate Raman detection. Because of the amplification produced by LRCA or ERCA and the enhanced Raman signal produced by multiple polyadenylates 340, 420 and/or Raman labels, detection of single copy biomolecules 130 is feasible using the disclosed methods, compositions and/or systems.

    摘要: The invention provides methods for analyzing the protein content of a biological sample, for example to obtain a protein profile of a sample provided by a particular individual. The proteins and protein fragments in the sample are separated on the basis of chemical and/or physical properties and maintained in a separated state at discrete locations on a solid substrate or within a stream of flowing liquid. Raman spectra are then detected as produced by the separated proteins or fragments at the discrete locations such that a spectrum from a discrete location provides information about the structure or identity of one or more particular proteins or fragments at the discrete location. The proteins or fragments at discrete locations can be coated with a metal, such as gold or silver, and/or the separated proteins can be contacted with a chemical enhancer to provide SERS spectra. Method and kits for practicing the invention are also provided.
