the aim of the present work was to prepare and characterize biopolymer nanocarriers and evaluate their suitability in possible oral delivery of insulin. the egg albumin biopolymer was used to prepare nanoparticles which were further characterized by fourier transformed infrared spectroscopy (ftir), transmission electron microscopy (tem), scanning electron microscopy (sem), zeta potential, dynam...

manganese zinc ferrite nanoparticles (mzf nps) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. to improve the colloidal stability of mzf nps for biomedical applications, nps were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (tpp) as crosslinker. the synthesized nps were characterized by x ray diffraction (xrd) analy...

Objective(s): To study the antimicrobial property of green synthesised silver nano metals with M.balbisiana, A.indica and O.tenuiflorm and their enhanced antibacterial activity, assessment of antimicrobial effect. And to explore the possible mechanism of AgNPs synthesis in the active constitutions of selected temperate plant extracts Materials and methods:Biosynthesis of AgNPs using plant extr...

We describe a light scattering apparatus based on a novel optical scheme covering the scattering angle range 0.5° ≤ θ ≤ 25°, an intermediate regime at the frontier between wide angle and small angle setups that is difficult to access by existing instruments. Our apparatus uses standard, readily available optomechanical components. Thanks to the use of a charge-coupled device detector, both stat...

Many drinkable dairy products added with green tea polyphenols have been launched by food industries because epidemiological studies suggest an association between the prevention of diseases and the consumption of polyphenol-rich beverages or foods. However, polyphenols have a significant affinity for proteins that leads to formation of soluble complexes, which can grow in size and even form se...

In this paper, aggregation behaviors of aqueous solutions of short chain hydrophilic Ionic Liquids (ILs), 1 – allyl - 3 - methylimidazolium chloride ([Amim]Cl), 1 - ethyl - 3 - methylimidazolium chloride ([Emim]Cl), 1 - butyl - 3 - methylimidazolium chloride ([Bmim]Cl), 1 - butyl - 3 - methylimidazolium tetrafluoroborate ([Bmim]BF4) were investigated using conductivity and laser ...
