    摘要: Metallic nanoclusters capable of providing an enhanced Raman signal from an organic Raman-active molecule incorporated therein are provided. The nanoclusters may be further functionalized, for example, with coatings and layers, such as adsorption layers, metal coatings, silica coatings, probes, 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 variety of organic Raman-active compounds and mixtures of compounds can be incorporated into the nanocluster.

    摘要: Epigenetic events such as DNA methylation play important roles in the regulation of gene expression. DNA methylation patterns have been found to differ between healthy and diseased tissue, such as healthy and cancerous tissue, thereby allowing DNA methylation to serve as a biomarker for disease states. Embodiments of the invention provide methods for detecting methylation patterns in DNA polymers. Methylation patterns are detected, in part, through the use of surface enhanced Raman spectroscopy (SERS). SERS provides a sensitive structure-based technique for chemical analysis.
