Journal ArticleDOI
Chitosan-based nanomaterials: A state-of-the-art review
TL;DR: Chitosan based nanomaterials have superior physical and chemical properties such as high surface area, porosity, tensile strength, conductivity, photo-luminescent as well as increased mechanical properties as comparison to pure chitOSan.
Journal ArticleDOI
Simultaneous determination of cholesterol, ascorbic acid and uric acid as three essential biological compounds at a carbon paste electrode modified with copper oxide decorated reduced graphene oxide nanocomposite and ionic liquid
TL;DR: The electrode, CuO-rGR/1M3OIDTFB/CPE showed remarkable sensitivities towards the determination of the analytes, and well defined and clearly separated oxidation peaks were obtained during their simultaneous analysis in a buffer solution at pH 7.4.
Journal ArticleDOI
Development of a sodium alginate-based organic/inorganic superabsorbent composite hydrogel for adsorption of methylene blue.
TL;DR: A very high adsorption capacity and a correlation coefficient of 0.998 calculated from isotherm equations show the high efficiency of the absorbent and thus expected to be a good candidate as an absorbent for water treatment.
Journal ArticleDOI
The determination of 2-phenylphenol in the presence of 4-chlorophenol using nano-Fe3O4/ionic liquid paste electrode as an electrochemical sensor
Hassan Karimi-Maleh,Colani T. Fakude,Nonhlagabezo Mabuba,Gbenga M. Peleyeju,Omotayo A. Arotiba +4 more
TL;DR: The sensor showed good recovery data for the analysis of 2-PP and 4-CL in orange rind, lemon rind and different water samples, which implies that the sensor can be used for the simultaneous determination of the two water contaminants.
Journal ArticleDOI
Electrochemical Aptasensor for Endocrine Disrupting 17β-Estradiol Based on a Poly(3,4-ethylenedioxylthiopene)-Gold Nanocomposite Platform
Rasaq A. Olowu,Omotayo A. Arotiba,Stephen Mailu,Tesfaye Waryo,Priscilla G. L. Baker,Emmanuel I. Iwuoha +5 more
TL;DR: The aptasensor was able to distinguish 17β-estradiol from structurally similar endocrine disrupting chemicals denoting its specificity to 17 β-est radiol.
