Spectrophotometric titration in near infrared region (Part 1)

An Anaerobic Titration Assembly for Spectrophotometric Use 1

Much useful information of a quantitative nature can be obtained with redox-active proteins by anaerobic titration with reducing substrates or chemical reductants such as sodium dithionite. We have used successfully for many years anaerobic spectrophotometer cells equipped with either two or four side arms from which known amounts of titrant can be added (1). This technique gives only a limited...

Near-infrared spectrophotometric determination of compositions of fullerene samples.

A novel method has been developed for the sensitive and accurate determination of compositions of fullerene samples. The method is based on the synergistic use of spectrophotometric measurements and partial least square method. The method is not only simple, inexpensive and fast but also is non-destructive. Compositions of various fullerene samples including fullerite which is the precursor to ...

Dual band complementary metamaterial absorber in near infrared region

brain near-infrared spectroscopy (nirs)

near-infrared spectroscopy (nirs) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum. typical applications include medical and physiological diagnostics. nirs can be used for non-invasive assessment of brain function through the intact skull in human subjects by detecting changes in blood hemoglobin concentrations associated with neural activity, e.g., ...

Evaluation of Polymethine Dyes as Potential Probes for Near Infrared Fluorescence Imaging of Tumors: Part - 1

Near-infrared (NIR) organic dyes have become important for many biomedical applications, including in vivo optical imaging. Conjugation of NIR fluorescent dyes to photosensitizing molecules (photosensitizers) holds strong potential for NIR fluorescence image guided photodynamic therapy (PDT) of cancer. Therefore, we were interested in investigating the photophysical properties, in vivo tumor-af...
