Surface Enhanced Spectroscopy-Active Composite Nanoparticles (SACN) comprising: core/shell nanoparticles comprising nanoparticle cores covered with shells, wherein the cores and the shells may comprise the same or different materials; at least one Raman-active reporter molecule associated with said core/shell nanoparticle; and an SiO2 encapsulant which encapsulates the core/shell nanoparticle and the at least one Raman-active reporter molecule, are described.

摘要:
An inline spectroscopic reader having a light source, one or more optics heads, a spectrometer and a data processing system in digital communication with the spectrometer detector. The optics heads include transmission optics providing for the illumination of a target with light from the light source and detection optics providing for the collection of light from the target. Typically, the target is moving with respect to the optics head during spectroscopic interrogation. The spectroscopic reader is thus an inline reader well suited to provide spectrum based production or analytical decision making in real time as the target moves along a production or analysis line. Also disclosed are methods including the steps of illuminating a target with light from a light source; collecting light from the target; obtaining a digitized spectrum with a spectrometer; extracting information content from the digitized spectrum; and basing a contemporaneous process decision upon the information content.

摘要:
An assay apparatus having a sample vessel within which an assay may be performed. The apparatus further includes a holder having a receptacle, socket or other device configured to operatively receive the sample vessel in a precise and easily repeated location with respect to the holder. A magnet may be operatively associated with the holder such that a magnetic field generated by the magnet intersects a portion of the sample vessel defining a magnetic concentration region within the sample vessel. A separate or integrated detection or interrogation instrument, typically a spectrometer, may be provided.
摘要:
A system and method for imaging a sample labeled with a material having a strong light scattering and reflecting properties are provided. A typical material having strong light scattering and reflecting properties is a metal colloid. The imaging system employs a light scattering and reflecting illumination technique. The sample can be imaged with reflection mode imaging along or with a combination of reflection mode and scatter mode imaging.
