Abstract The feasibility of using the tris-2-2′-bipyridine ruthenium (III) (Ru(bpy)3 3 +) chemiluminescent (CL) reaction for detection amino acids, peptides, and proteins has been studied. Detection limits acids as determined by flow injection analysis (FIA) ranged from 20 pmol proline to 50 nmol asparagine. In general, containing secondary amine groups yielded strongest responses. A mechanism Ru (bpy)3 + chemiluminescence aliphatic amines proposed. Studies peptide molecules poly-prolines...
The structural stability of cytochrome c has been studied in alkylammonium formate (AAF) ionic liquids such as methylammonium (MAF) and ethylammonium (EAF) by fluorescence circular dichroism (CD) spectroscopy. At room temperature, the native structure is maintained relatively high liquid concentrations (50−70% AAF/water or AAF/phosphate buffer pH 7.0) contrast with denaturation similar solutions methanol acetonitrile water cosolvents. Fluorescence CD spectra indicate that conformation 20%...
Favipiravir is a potential antiviral medication that has been recently licensed for Covid-19 treatment. In this work, gadolinium-based magnetic ionic liquid was prepared and used as an extractant in dispersive liquid-liquid microextraction (DLLME) of favipiravir human plasma. The high enriching ability DLLME allowed the determination real samples using HPLC/UV with sufficient sensitivity. effects several variables on extraction efficiency were investigated, including type extractant, amount...

We studied the use of dimethyl carbonate (DMC) as a non-toxic, aprotic modifier for hydrophilic liquid interaction chromatography (HILIC) and normal-phase (LC). A comparison ethyl acetate (EA) DMC organic mobile-phase modifiers in hexane LC phthalates was conducted with silica column showed that retention factors (k) at same percentage were about factor two greater DMC. Detection 215 nm, possible DMC, allowed better detection by 10, compared EA detection, best 254 nm wavelength. Using...
