Validation of manufacturing process of Diltiazem HCl tablets by NIR spectrophotometry (NIRS)

Journal of Pharmaceutical and Biomedical Analysis, 2007
The goal of this study was to apply the Process Analytical Technology FDA's initiative in pharmaceutical tablets manufacturing. Near Infrared Spectrophotometry (NIRS) was used as a non-destructive, very fast technique requiring no sample preparation. Direct compression powder blends containing Diltiazem HCl as a model drug were pressed into tablets for

Single-Trial NIRS Data Classification for Brain–Computer Interfaces Using Graph Signal Processing

IEEE transactions on neural systems and rehabilitation engineering, 2018
Near-infrared spectroscopy (NIRS)-based brain–computer interface (BCI) systems use feature extraction methods relying mainly on the slope characteristics and mean changes of the hemodynamic responses in respect to certain mental tasks.

Neuro-NIRS: Analysis of Neural Activities Using NIRS

2009
Analysis method for quick component of NIRS is explained. In order to compare quantitatively the amount of quick component, absolute average operation is applied. The result Q is then formulated as the product of magnitude M and density D. By characteristic differences of M and D functional features of each channel are discussed.

Upconverting and NIR emitting rare earth based nanostructures for NIR-bioimaging

Nanoscale, 2013
In recent years, significant progress was achieved in the field of nanomedicine and bioimaging, but the development of new biomarkers for reliable detection of diseases at an early stage, molecular imaging, targeting and therapy remains crucial. The disadvantages of commonly used organic dyes include photobleaching, autofluorescence, phototoxicity and ...

NIR-Spektroskopische Analytik

1994
Elektromagnetische Strahlung kann auf vieWielfaltige Art mit der Materie wechselwirken. Infrarotstrahlung — elektromagnetische Strahlung im Wellenlangenbereich von 800 bis 200000 nm — kann unter bestimmten Voraussetzungen Schwingungen anregen. Im fernen Infrarot — 25000 bis 200000 nm — konnen dies z.B.

A NaYbF4: Tm3+ nanoprobe for CT and NIR-to-NIR fluorescent bimodal imaging

Biomaterials, 2012
Early diagnosis that combines the high-resolutional CT and sensitive NIR-fluorescence bioimaging could provide more accurate information for cancerous tissues, which, however, remain a big challenge. Here we report a simple bimodal imaging platform based on PEGylated NaYbF(4): Tm(3+) nanoparticles (NPs) of less than 20 nm in diameter for both CT and ...

On the terminology of the spectral vegetation index (NIR − SWIR)/(NIR + SWIR)

International Journal of Remote Sensing, 2011
The spectral vegetation index (ρNIR − ρSWIR)/(ρNIR + ρSWIR), where ρNIR and ρSWIR are the near-infrared (NIR) and shortwave-infrared (SWIR) reflectances, respectively, has been widely used to indicate vegetation moisture condition. This index has multiple names in the literature, including infrared index (II), normalized difference infrared index (NDII)

Clinical Application of NIRS

2013
Near-infrared spectroscopy (NIRS) has several significant advantages over existing radiological techniques in clinical application. Humans do face any accumulation of deleterious x-rays. Unlike ultrasound methods, NIRS does not lead to excess heat, can differentiate between human tissues with varying optical absorption or scatter, can provide ...
