Sampling procedures for cleaned surfaces can be divided into four types. Direct surface sampling involves a fiberoptic probe (such as a near infrared probe) that is placed directly on the surface. An output is provided... 

Although a lot of information can be obtained with the analysis of diluted polymer lattices samples, as shown previously, the advantages that in situ analysis of the emulsion polymerization processes represent over systems that require dilution are well documented. A dilution step implies sample manipulation and increased measurement dead times. Therefore, regardless the effectiveness of the dilution strategy, there is incentive in continuing the development of in-line and in-situ measurement probes. Of the light based techniques reported only Raman and Near Infrared probes have been used for in situ to monitor conversion." The use of light and specifically fiber optic probes as a particle concentration and particle size detectors is a concept that has become widely accepted. ...

An interesting imaging probe Id that can selectively target bacteria was recently reported by Smith et al. [31] also based on a heptamethine chromophore. The probe is composed of a bacterial affinity group, which is a synthetic zinc (II) coordination complex that targets the anionic surfaces of bacterial cells and a near infrared dye. The probe allowed detection of Staphylococcus aureus in a mouse leg infection model using whole animal near-infrared fluorescence imaging.

Dramatic advances in modem fluorophore technology have been achieved with the introduction of Alexa Fluor dyes by Molecular Probes (Alexa Fluor is a registered trademark of Molecular Probes). Alexa Fluor dyes are available in a broad range of fluorescence excitation and emission wavelength maxima, ranging from the ultraviolet and deep blue to the near-infrared regions. Because of the large... 

Transitions between different electronic states result in absorption of energy in the ultraviolet, visible and, for many transition metal complexes, the near infrared region of the electromagnetic spectrum. Spectroscopic methods that probe these electronic transitions can, in favourable conditions, provide detailed information on the electronic and magnetic properties of both the metal ion and its ligands.
