In order to investigate chitosan and magnesium-nano fertilizers’ impact on photosynthetic pigments, protein, proline, and soluble sugar contents of sesame under irrigation cut-off treatment, a split-factorial experiment was conducted based on randomized blocks with three replications. Irrigation cut-off based on BBCH sca...

Objective(s): Design and construction of biocompatible and biodegradable scaffolds are among the main goals of tissue engineering. Recently, use of nano-hydroxyapatite as a bioactive bioceramic agent with high similarity to the mineral phase of the human bone tissue, in combination with biodegradable polymers and implant coatings has attracted the attention of researchers in the field of biomat...

Abstract The remediation of methylene blue from wastewater using chitosan-sunflower-nano-iron (CSN) beds was examined in this study with the Fenton process. Nano-iron is synthesized green synthesis Then, biopolymer obtained nano-iron, sunflower tray waste, and chitosan. These used process for removing Methylene (MB) water. Beds dye are characterized SEM, TEM, FTIR, XRD techniques. For method op...

Electrofluidodynamics techniques (EFDTs) are emerging methodologies based on liquid atomization induced by electrical forces to obtain a fine suspension of particles from hundreds of micrometers down to nanometer size. As a function of the characteristic size, these particles are interesting for a wide variety of applications, due to the high scalability of chemical and physical properties in c...

Optical properties of spin-cast chitosan films have been determined in the infrared, visible, and ultraviolet region of the spectrum using spectroscopic ellipsometry. Optical constants for the UV-vis-near IR spectra from 130 to 1700 nm were determined using Cauchy dispersion forms combined with Lorentzian oscillator models in the absorptive shorter wavelength regions. Infrared index of refracti...

Biopolymers are promising materials in the delivery of protein drugs due to their compatibility, degradation behavior, and nontoxic nature on administration. On suitable chemical modification, these polymers can provide better materials for drug delivery systems. Nanostructured drug carriers allow the delivery of not only small-molecule drugs but also of nucleic acids and proteins. The use of b...

Oral insulin delivery that better mimics physiological pathways is a necessity as it ensures patient comfort and compliance. A system which is based on a vehicle of nano order where positively charged chitosan interacts with negatively charged insulin and forms a polyelectrolyte complex (PEC) solubilizate, which is then solubilized into an oily phase of oleic acid, labrasol, and plurol oleaque-...

A novel Ag2O/TiO2-modified chitosan-based photocatalytic film with high adsorption and photocatalytic activity was synthesized under simulated solar irradiation, based upon the coupling of the synergistic catalytic technique of nano Ag2O/TiO2 and membrane separation. XRD, XPS, FESEM, and TEM characterization results illustrated that the Ag2O nanoparticles with a small size of 3–5 nm deposited o...

Melanoma is the most aggressive form of skin cancer and various treatments have been investigated to treat this disease, but drug resistance remains an important factor in failure conventional therapeutics. Here we describe development, optimisation characterisation alginate, chitosan, pullulan, their combined nano-emulsions as delivery platforms for potential application melanoma. A novel nano...

A novel, sensitive and effective method has been developed for preconcentration of Ni on C18 disks modified cyclodextrin–chitosan/nano graphene oxide. Simple chemical bonding method to synthesize cyclodextrin–chitosan/nano graphene oxide (CCGO) was reported. The adsorption behaviors of Ni (II) in aqueous solution on CCGO were systematically investigated. The procedure is based on the selective ...
