Abstract:
The present research work was carried out in order to develop simple, accurate and precise UV sprctrophotometric methods having comparable sensitivity as that of sophisticated chromatographic techniques. Two methods were developed namely first derivative spectrophotometry and ratio spectra derivative spectrophotometry for accurate determination of specified impurity methimazole (imp A) in presence of drug carbimazole. First derivative spectrophotometric method involves recording of zero order spectra of both the drugs carbimazole and methimazole and its mixture in the range of 200-400 nm and s

Abstract:
The present work describes the application of spectrophotometric method for the determination of manganese (Mn) used in water samples collected from the coastal zone of the Black Sea. We studied a colorimetric method for the determination of manganese using UVVIS molecular absorption spectrophotometry. We measure absorbance of the 450 nm charge transfer band of permanganate. In all analysed samples we found that the levels of manganese did not exceed the pollution threshold.

Abstract:
The interaction of native calf thymus DNA with the anti-hyperthyroid drug methimazole was investigated by different spectroscopic (UV-Vis spectrophotometry, spectroflourimetry, and circular dichroism), electrochemical (cyclic voltammetry and chronoamperometry) methods, and molecular docking calculations. The binding constant (Kb) obtained from the spectrophotometric method was 9.67 × 103 L mol−1, comparable with that of groove binding molecules. The binding mode was further investigated by following the competition between Hoechst 33258 and methimazole for DNA grooves by spectrofluorimetry. Co

Helicoverpa armigera is an insect, causes important economical losses in crops. To reduce this loss, chemical insecticides such as pyrethroids have been commonly used against H. armigera in farming areas all over the world. However, excess and continuous usages of them cause resistance development in H. armigera. Insects develop resistance against applied insecticides by following three main mechanisms<br>by reducing the amount of insecticide entering into the insect body, developing insensitivity of the insecticide effective site and increasing detoxification metabolism of insecticides such a

These molecules are a class of compounds synthesized conjugating a unit of lactose to specifically modified disperse chromophores. The presence of lactose enhances the water solubility of these molecules, and also makes these compounds amphiphiles. The amphiphilicity allows the self-assembly of glycoconjugated dyes in solution. The behavior of these molecules in solution was studied experimentally using a variety of techniques, including UV-Visible spectroscopy, Dynamic Light Scattering (DLS) and Small Angle X-Rays Sc
