Design- Experimental Study Animals- Seventy-two male Wistar rats Procedures- Animals were randomized into six groups of 12 animals each. Group I: Animals with created wounds and no...

background and objectives: the most prevalent and worldwide oral disease is dental caries that affects a significant pro- portion of the world population. there are some classical approaches for control, prevention and treatment of this pathologic condition; however, the results are still not completely successful. therefore new methods are needed for better management of this important challen...

Functionalize nano-architecture CaO/Ag-chitosan bio-nanoparticles were prepared by the acetic acid sol-gel process and loaded into chitosan nanocomposite. The so bioactive nano-CaO/Ag-chitosan nanocomposite was characterized using XRD, TEM, FE-SEM, optical, antimicrobial activity evaluated. antibacterial evaluations implied that chitosan, nano-CaO, are exhibited subtle activities against both G...

Objective- The healing effect of chitosan supported cerium oxide nanoparticles (nano-CeO2) on cutaneous experimental excisional wound infected with pseudomonas aeruginosa was studied in rat. Design- Experimental Study. Animals- Sixty male albino rats. Procedures- The chitosan supported nano-CeO2 hydrogel was prepared and characterized using Fourier-transform infrared spectro...

Objective(s): Binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. Materials and Methods: Template free ZSM-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/ZSM-5 hybrid composites with nano chitosan...

Using bioactive and biocompatible coatings to biofunctionalized metallic implant surfaces for enhanced bone regeneration while resisting bacterial infection has attracted materials scientists' interest. Bio-metallic Ti-25Zr disc sample was prepared using powder metallurgy then coated an electrospinning method form a nanocomposite fiber as coating layer over the surface of metal alloy substrate....

A new family of biodegradable polymer/bioactive glass (BG) composite materials has emerged based on the availability of nano-sized bioactive particles. Such novel biocomposites can have enhanced performance, in terms of mechanical properties and bioactivity, and they can be designed to be used in bone regeneration approaches. In this work, membranes of chitosan (CTS) and chitosan with bioactive...

The development of rapid and reliable processes for the synthesis of nano materials is of great importance in the field of nanotechnology. In this paper, the synthesis of Chitosan/TiO2 nanocomposites was carried out by using LPD technology in aqueous medium. The method was performed by mixing the chitosan with TiO2 in the presence of polyvinyl alcohol as the capping agent. In this work, Chitosa...

Encapsulation and immobilization technology is important for the food processing and bioengineering industries. Chitosan is a natural polysaccharide prepared by the N-deacetylation of chitin. It has been widely used in food and bioengineering industries, including the encapsulation of active food ingredients, in enzyme immobilization, and as a carrier for controlled drug delivery, due to its si...
