    摘要: Composite organic-inorganic nanoparticles (COIN) and clusters of such nanoparticles are provided that produce surface-enhanced Raman signals when excited by a laser. The nanoparticles include metallic colloids and a Raman-active organic compound. The metal required for achieving a suitable SERS signal is inherent in the nanoparticle, and a wide variety of Raman-active organic compounds can be incorporated into the particle. Methods for producing the nanoparticles and clusters of nanoparticles are also provided. In addition, polymeric microspheres containing the nanoparticles and clusters of nanoparticles and methods of making them are also provided. Methods for using the nanoparticles, clusters, and microspheres in assays for multiplex detection of biological molecules do not require signal amplification techniques.

    摘要: Composite organic-inorganic nanoparticles (COIN) are provided that produce surface-enhanced Raman signals when excited by a laser. The nanoparticles include metallic colloids and a Raman-active organic compound. The metal required for achieving a suitable SERS signal is inherent in the nanoparticle, and a wide variety of Raman-active organic compounds can be incorporated into the particle. Indeed, a large number of unique Raman signatures can be created by employing nanoparticles containing Raman-active organic compounds of different structures, mixtures, and ratios. Thus, nanoparticles and methods described herein are useful for the simultaneous detection of many analytes in a mixture, resulting in rapid qualitative analysis of a mixture. In addition, since many Raman-active organic compounds can be incorporated into a single nanoparticle, the SERS signal from a single COIN particle is strong relative to SERS signals obtained from Raman-active materials that do not contain the nanoparticles described herein.

    摘要: The methods and apparatus disclosed herein are of use for sequencing and/or identifying nucleic acids. Nucleic acids containing labeled nucleotides may be synthesized and passed through nanopores. Detectors operably coupled to the nanopores may detect the labeled nucleotides. By determining the time intervals at which labeled nucleotides are detected, distance maps for each type of labeled nucleotide may be compiled. The distance maps in turn may be used to sequence and/or identify the nucleic acid. In different embodiments of the invention, luminescent nucleotides or nanoparticles may be detected using photodetectors or electrical detectors. Apparatus and sub-devices of use for nucleic acid sequencing and/or identification are also disclosed herein.
