    摘要： An optically active particle and a method of manufacturing said particles, plus methods of tagging a material of interest with said particles are disclosed. The particle comprises a surface-enhanced spectroscopy (SES) active core and a SES active reporter associated with the SES core wherein the particle produces a measurable and thermally stable SES spectrum upon optical interrogation. As used in the disclosure, thermally stable may be defined as maintaining a measurable SES spectrum after the particle or any material tagged with the particle has been exposed to a temperature substantially higher than room temperature.

    摘要： Embodiments include a particle comprising a surface enhanced spectroscopy (SES)-active core and a SES-active reporter molecule associated with the SES-active core wherein said particle has a measurable SES spectrum when excited by incident light having a wavelength of at least 1400 nm. Alternative embodiments include methods of manufacturing said particle and methods of tagging a material with said particle. The particle may include an SES-active core which supports plasmon resonance at a wavelength of at least 1400 nm. The particle may comprise an anisotropic core. The particle may include an SES-active reporter molecule which is resonant at one or more wavelengths greater than or equal to 1400 nm.

    摘要： One embodiment is a SERS enhancing substrate which includes a porous substrate and a Raman enhancing material associated with a surface of the porous substrate. The Raman enhancing material may be a Raman enhancing metal or other Raman enhancing material. The Raman enhancing material may also be configured to improve binding of a taggant to the substrate. The substrate described above may be included in a sample vessel useful for the flow-through analysis of large sample volumes, or for the rapid analysis of very dilute samples. Other embodiments include methods and systems for detecting taggants with SERS and similar techniques.

    摘要： A catalytic nanotemplate including a freestanding template particle and a director associated with the surface of the freestanding template particle. The free standing template particle may have multiple segments and the director may be associated with one or more of the segments. In instances where multiple segments are present, the segments may be made of different materials or be of the same material in different forms. More than one type of director or no director may be associated with any particular segment.
