The invention provides a method for enhancing the durability of a titanium dioxide material, the method including mixing citric acid and an alumina source with an aqueous slurry of titanium dioxide particles and water to form a mixture, the mixture having an acidic pH; and raising the pH of the mixture to a pH of no more than about 7.5 to form alumina-coated titanium dioxide particles. The invention also provides a pigmented plastic article including alumina-coated titanium dioxide particles prepared according to the invention dispersed in a polymer material.

A multi-dispersive spectrometer is provided in which the spectrometer comprises an optical system configured to direct an excitation signal from an excitation light source toward a sample, receive a spectroscopy signal from the sample, and direct the spectroscopy signal toward the detector. The optical system comprises a movable optical component adapted to move the spectroscopy signal relative to at least one sensor of the detector and the detector is adapted to detect a plurality of discrete shifted spectroscopy signals. A method of obtaining a Raman spectrum from a sample is also provided. The method comprises directing an excitation signal from an excitation light source toward a sample; receiving a spectroscopy signal from the sample; and directing the spectroscopy signal toward a detector, wherein the spectroscopy signal is moved relative to at least one sensor of the detector to provide a plurality of discrete shifted spectroscopy signals.

Multi-dispersive spectrometer

A spectrometer is provided. In one implementation, for example, a spectrometer comprises an excitation source, a focusing lens, a movable mirror, and an actuator assembly. The focusing lens is adapted to focus an incident beam from the excitation source. The actuator assembly is adapted to control the movable mirror to move a focused incident beam across a surface of the sample.

Spectrometer

A spectrometer, such as a Raman spectrometer, adapted for analyzing a complex sample is provided. In an example implementation, the spectrometer may be able to determine one or more spectral characteristics of an inner subsurface layer or region of a complex sample (e.g., contents of a container). In one embodiment, for example, A spectrometer includes an excitation source configured to provide an excitation signal; an optical system configured to direct the excitation signal toward a sample and receive a spectroscopy signal from the sample. The optical system may include a spatial filter configured to separate or isolate at least one first portion of the spectroscopy signal from at least one second portion of the spectroscopy signal and pass the at least one first portion of the spectroscopy signal. A detector is configured to determine at least one spectral feature of the at least one first portion of the spectroscopy signal.

A spectroscopic assay is provided. The assay comprises: a motive particle configured to move within a solution, the motive particle comprising a first analyte binding reagent for selectively binding to a target analyte; and a spectroscopic reporter particle configured to provide a predetermined spectroscopic signal in response to being interrogated by a spectrometer, the spectroscopic reporter particle comprising a second analyte binding reagent for selectively binding to the target analyte, wherein the motive particle and the spectroscopic reporter particle are configured to provide a sandwich assay in the presence of the target analyte via the first and second analyte binding reagents.

Spectroscopic assays and tagging

Spectrometers and methods for determining the presence or absence of a material in proximity to and/or combined with another material are provided. In one particular example, a spectrometer is provided that includes a light source, a detector and an optical system. In this implementation, the light source is configured to provide an excitation incident beam. The detector is configured to detect a spectroscopy signal. The optical system is configured to direct the excitation incident beam toward a sample at a non-zero angle from a zero-angle reference. The optical system is further configured to receive a spectroscopy signal from the sample and provide the spectroscopy signal to the detector. The detector is configured to remove a spectral interference component of the spectroscopy signal.
