    摘要: A programmable Raman transducer is disclosed for detecting the presence or absence of a preselected compound in a sample. The transducer, in a preferred embodiment, includes a laser source for generating laser light for illuminating the sample. Collector optics, absent a spatial filter, are used for collecting Raman-scattered light from the sample. A detector generates spectral data from the Raman-scattered light, and a digital processor compares the spectral data to a database of spectral data on selected compounds, including the preselected compound to generate a binary signal indicating presence or absence of the preselected compound.

    摘要: A method is disclosed for analyzing keratinized tissue, particularly fingernails, of a subject to diagnose osteoporosis and bone fracture risk. A Raman spectrum of a sample of keratinized tissue is generated. Broad spectral background features of the spectrum are removed, preferably by using Fourier transform analysis. Peak heights of Raman features of interest, particularly the S—S bond of cystine, are measured. These peak height measurements are normalized using reference peak heights of Raman features that are invariant between normal and osteoporotic subjects, such as the CH2 bending peak.
