Food grade micro- or nano-carrier systems (NCS) are being developed to improve the controlled release of antimicrobial agents. To augment the stability of liposomal NCS and to overcome the limitations associated with the use of free bacteriocin (nisin) in the food system, multi-component colloidosomes (MCCS) were developed by electrostatic interactions between anionic alginate and cationic chit...

Study of biophysical interactions have been carried out using specific combination of proteins such as Brucella abortus cell envelop protein (as antigen) and its complementary antibody (raised in mice and rabbit). A best optimized composition of biocompatible CeO2 nano-octahedra and other biocompatible materials (chitosan) was used in this study. Linear range was found in the range of 6.25 μg/m...

The current study aims to evaluate the adsorption of lead element in aqueous solution by using a nano-material consisting mixture reduced graphene oxide and nano-chitosan, which was prepared 1:1 ratio. And an X-ray diffraction device for studying crystal structure nanomaterials. results showed that percentage removal increases with increasing concentration nanomaterial under constant conditions...

An opaque, white chitosan/ Hydroxyapatite nanocomposite was prepared by a simple blend method. Morphology, pore size and dispersion of nano-hydroxyapatite in chitosan matrix were visualized using SEM images. The FTIR with EDX analysis confirmed the bony apatite layer formed on outside composite. Porosity measurements water uptake studies evaluated which revealed maximum porosity 80% to 92% chit...

Despite the merits of glass ionomer cements (GICs), they suffer from weak mechanical properties such as low wear resistance. In this study, the mechanical properties of GICs after incorporating chitosan and nano-hydroxyapatite was investigated. The samples were prepared in four groups, including non-modified GIGs (NMGIC, n = 5), chitosan incorporated GICs (CHGIC, n = 5), nano-hydroxyapatite inc...

Omega-3 rich fish oils are extremely labile, thus requiring control of oxidation and off flavor development. A recently proposed emulsification method, layer-by-layer (LbL) deposition, was found to be a plausible method to enhance the characteristics of bioactive ingredients, especially lipids. The present work was designed to test the possibility of enhancing the uptake and utilization of omeg...

In this research, polyvinyl alcohol (PVA)-chitosan composite films were produced using nanocellulose from coconut fibers (Cocos nucifera) in an Indonesian plantation order to enhance mechanical properties and biodegradability. The process began by separating lignin hemicellulose delignification, bleaching, then cellulose hydrolysis produce nanocellulose. PVA was mixed with chitosan specific com...

Purpose Paper aims to evaluate the efficiency of traditional chitosan, nano and chitosan nanocomposites for consolidating aged papyrus samples. Cellulose-based materials, such as sheets paper, which are most common types writing supports works art in many museums archive. They subjected different deterioration factors that may lead conservation problems. Consolidation treatment is one treatment...
