A recently created tissue demonstrative technique, in light of label-free close infrared (NIR) polarimetric reflectance imaging for the characterization of histopathological tests of lung cancer cells, is displayed. The design, calibration, and testing of an automated NIR polarimetric imaging framework, with accentuation on lung cancer location, are advanced in detail. The depicted electro-opti...

We propose to employ near-infrared (NIR) images for face recognition in reduced illumination or total darkness. A homomorphic processing technique has been developed to effectively reduce the artifact of NIR images [1]. In this paper, we proceed to construct a facial feature detection system that would function independent of the surrounding lighting condition. Firstly, we propose a classificat...

Responsive systems sensitive to near-infrared (NIR) light are promising for triggered release due to efficient deep tissue penetration of NIR irradiation relative to higher energy sources (e.g., UV), allowing for spatiotemporal control over triggering events with minimal potential for tissue damage. Herein, we report star polymers containing thermally-labile azo linkages that dissociate during ...

The purpose of this review article is to outline recent progress in near-infrared (NIR) spectroscopy. Some particular emphasis is put on the delineation of its versatility in analytical chemistry. NIR spectroscopy is versatile in many aspects. For example, it is electronic spectroscopy as well as vibrational spectroscopy. It is also all-round in applications from basic to practical applicat...

A gold nanoshell-functionalized polymer multilayer nanorocket performs self-propulsion upon the irradiation with NIR light in the absence of chemical fuel. Theoretical simulations reveal that the NIR light-triggered self-thermophoresis drives the propulsion of the nanorocket. The nanorocket also displays -efficient NIR light-triggered propulsion in -biofluids and thus holds considerable promise...

the potential of fourier transform near-infrared (ft-nir) spectroscopy technique was applied to determine moisture and soluble solids content of shahani date fruit. spectral acquisitions were carried out in reflectance mode using a ft-nir spectrophotometer in the range of 12000- 4000cm-1. three different preprocessing methods namely: multiplicative scatter correction (msc), first and second der...

BACKGROUND The use of near-infrared (NIR) fluorescence imaging techniques has gained great interest for early detection of cancer because water and other intrinsic biomolecules display negligible absorption or autofluorescence in this region. Novel fluorescent nanoparticles with potential to improve neoplasm detection sensitivity may prove to be a valuable tool in early detection of colon tumor...

Near-infrared photoimmunotherapy (NIR-PIT) is a newly-established cancer treatment which employs the combination of an antibody-photoabsorber conjugate (APC) and NIR light. When NIR light is absorbed by APC-bound tissues, a certain amount of heat is generated locally. For the most part this results in a subclinical rise in skin temperature, however, excessive light exposure may cause non-specif...

BACKGROUND NIR was identified as an inhibitor of histone acetyltransferase and it represses transcriptional activation of p53. NIR is predominantly localized in the nucleolus and known as Noc2p, which is involved in the maturation of the 60S ribosomal subunit. However, how NIR functions in the nucleolus remains undetermined. In the nucleolus, a 47S ribosomal RNA precursor (pre-rRNA) is transcri...

The application of surface plasmon resonance (SPR) measurements to the study of ultrathin organic and inorganic films adsorbed onto gold surfaces utilizing nearinfrared (NIR) excitation from 800 to 1152 nm is described. SPR scanning angle measurements of film thickness are demonstrated at 814 and 1152 nm using lowpower diode and HeNe laser sources, respectively. Several advantages of SPR in the...
