Evaluating a novel method for vitamin A analysis in an observational study of the UAE's obese population.

Vitamin A plays a critical role in various biological functions, including vision, cellular differentiation, and immune regulation. However, accurately assessing its status, particularly in obese individuals, presents challenges due to potential alterations in metabolism and distribution. This study utilized Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) methodology to precisely measure serum vitamin A concentrations in population of UAE.

Electrochemical Sensor for Detection and Degradation Studies of Ethyl Violet Dye.

In this work, a simple and sensitive electrochemical method was developed to determine ethyl violet (EV) dye in aqueous systems by using square wave anodic stripping voltammetry (SWASV) employing a glassy carbon electrode modified with acidic-functionalized carbon nanotubes (COOH-CNTs). In square wave anodic stripping voltammetry, EV exhibited a well-defined oxidation peak at 0.86 V at the modified GCE.

A designed miniature sensor for the trace level detection and degradation studies of the toxic dye Rhodamine B.

The presence of organic pollutants in water and food samples is a risk for the environment. To avoid this hazard a variety of analytical tools are used for the detection of toxic organic contaminants. Herein we present a selective and sensitive electrochemical sensor based on amino group functionalized multi walled carbon nanotubes and carboxylic group functionalized multi walled carbon nanotubes (HOOC-MWCNTs/NH-MWCNTs) as modifiers of the glassy carbon electrode for the detection of a toxic dye, Rhodamine B.
