Objective(s): Chitosan nanoparticles (CNPs) were prepared based on the ionic gelation of chitoan with anionic compounds of Ocimum basilicum leaf extract. Materials and Methods: After addition of Ocimum basilicum leaf extract to chitosan solution, the physicochemical properties of the nanoparticles were determined by Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared...

Recent developments in processing techniques and detection hardware have opened new horizons for the application of light scattering methods based on the dynamic analysis of coherent scattered light. Increased computational power of modern microprocessors allow real-time data evaluation on standard desktop computers. The continuous improvement of detector arrays, such as cameras based on CCD or...

The utility of calcium oxide nanoparticles in the biomedical and physical fields has instigated their biocompatible synthesis production. Moreover, it is important to investigate biocompatibility at molecular level for ecotoxicological concern. This study explores green (CaONP) using Crescentia cujete leaf extract. synthesized CaONP were found have a size 62 ± 06 nm hydrodynamic diameter 246 12...

The synthesis and characterization of nanoparticles comprising a polymer core and a silica shell, with and without a silane-coupling agent between the core and the shell, is presented in this paper. The first step in the nanoparticle synthesis is a “surfactant free” radical suspension polymerization in water of monomeric units of methylmethacrylate in the presence of methoxypolyethilene glycol ...

Biocompatible hydroxyapatite nanocomposites are biocompatible, biodegradable and nontoxic have been paid many attentions as one of the most suitable vehicle for drug delivery use. Our objective in this work was to prepare and characterize caseins based HA nanocomposite in a colloidal form for drug delivery purposes. Casein biopolymer was firstly extracted from skimmed milk by adding acetic acid...

The morphological properties of cellulose nanofibrils obtained from eucalyptus pulp fibres were assessed. Two samples were produced with the same chemical treatment (NaClO/NaBr/TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical) oxidation), but distinct mechanical treatment intensities during homogenization. It was shown that the nanofibrils production yield increases with the mechanical energ...

Green synthesis of silver nanoparticles (AgNPs) has attracted substantial interest and achievement due to their environmental friendliness, ease manipulation, potential for large-scale production. By using aqueous Camellia sinensis leaf extract, suspensions AgNPs, which possess photocatalytic biological activity, were successfully synthesized in this study. The reduction ions AgNPs was visually...

Butyl oleate synthesis by the lipase B from Candida antarctica (CalB) under extreme halophilic conditions was investigated in present research through AOT/Water/Isooctane reverse micellar system. The impact of aqueous content (Wo=H2OSurfactant) and NaCl variation on enzymatic activity CalB butyl reaction micelles explored. results indicated that, based increase NaCl, it is remarkable to achieve...

Chondroitin sulphate (CS) is a linear sulfated polysaccharide found in cartilage and other tissues in the body. Small angle neutron scattering (SANS) and dynamic light scattering (DLS) measurements are made on semi-dilute CS solutions to determine ion induced changes in the local order of the CS chains and in their dynamic properties. In salt-free CS solutions SANS detects the correlation peak ...
