  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • Simple and sensitive detection of cyanide using pinhole shell-isolated nanoparticleenhanced Raman spectroscopy

    Cyanide is a great threat to public health, environmental safety and homeland security because of its extremely high toxicity and widespread usage in industry. Countering such a threat can be greatly aided by a rapid, sensitive, on-site detection method. Here, a pinhole shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) technique for cyanide sensing has been established, and a ...

  • Mixture analysis using reverse searching and non-negative least squares

    The portable even handheld Raman spectrometer can provide adequate spectral resolution for material identification in situ. Raman spectra are information rich but not easy to interpret, especially for the spectra of mixtures. The ability to identify components in the mixture is, therefore, of considerable interest and challenge. In this study, a promising solution for rapid mixture identification ...
