abstract: camel milk contains sufficient levels of insulin and does not form the coagulum in the stomach preventing degradation of insulin and act as an effective vehicle to take the milk insulin unchanged to the intestine. in present study direct spectroscopy and standard addition method, well-known methods in analytical chemistry were used for determining insulin concentration in camel milk. ...

Galctose oxidase nanoaggregates have been prepared by chemical desolvation method involving the crosslinkng agent glutaraldehyde. These enzyme nanoagregates have been characterized by transmission electron microscopy(TEM), UV visible spectroscopy, Fourier transform infrared spectroscopy (FTIR). TEM reveals the globular spherical nanostructured form upto the range of 20nm. UV visible spectroscop...

In this study, visible-near infrared spectroscopy and mid-infrared spectroscopy were compared to evaluate their applicability in classifying citrus leaves infected with canker and Huanglongbing (HLB) from healthy citrus leaves. The visible-near infrared spectra in the range 350-2,500 nm and mid-infrared spectra in the range of 5.15-10.72 μm were collected from healthy and diseased (canker, HLB)...

The construction and design of a microscope coupled with a miniature UV-vis spectrometer is described. This was applied to the study of dyes linked to solid supports and displayed good correlation in spectral shape and lambda(max) values when compared to the dyes in solution, as well as showing a linear relationship between dye loading and UV-vis absorbance. The spectral profiles of these dyes ...

Optical coherence correlation spectroscopy (OCCS) allows studying kinetic processes at the single particle level using the backscattered light of nanoparticles. We extend the possibilities of this technique by increasing its signal-to-noise ratio by a factor of more than 25 and by generalizing the method to solutions containing multiple nanoparticle species. We applied these improvements by mea...

Here we present a method to produce TiO2 nanocrystals coated by thin layer of graphitic carbon. The coating process was prepared via chemical vapor deposition (CVD) with acetylene used as a carbon feedstock with TiO2 used as a substrate. Different temperatures (400°C and 500°C) and times (10, 20, and 60 s) of reaction were explored. The prepared nanocomposites were investigated by means of tran...
