    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 single spectrum is taken to detect multiple reporter signals. The spectrum is deconvoluted by experimentally trained software to identify multiple analytes.

    摘要: Disclosed herein are a Raman spectroscopy structure comprising a porous material substrate, and a method of performing Raman spectroscopy of a sample disposed adjacent to the structure comprising the porous material substrate. Generally, the substrate includes one or more layers of a porous material such as porous silicon, porous polysilicon, porous ceramics, porous silica, porous alumina, porous silicon-germanium, porous germanium, porous gallium arsenide, porous gallium phosphide, porous zinc oxide, and porous silicon carbide. It has been discovered that such a substrate material, when excited with near-infrared light, does not exhibit undesired background fluorescence characteristic of other known Raman spectroscopy substrates.
