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...

A potentiometrically tuned-glucose biosensor was fabricated using core-shell nanocomposite based on zinc oxide encapsulated chitosan-graft-poly(vinyl alcohol) (ZnO/CHIT-g-PVAL). In a typical experiment, ZnO/CHIT-g-PVAL core-shell nanocomposite containing <20 nm ZnO nanoparticles was synthesized using wet-chemical method. The glucose responsive bio-electrode, i.e., glucose oxidase/ZnO/chitosan-g...

Controlling cell adhesion on a biomaterial surface is associated with the long-term efficacy of an implanted material. Here we connect the material properties of nanocomposite films made from PEO physically cross-linked with layered silicate nanoparticles (Laponite) to cellular adhesion. Fibroblast cells do not adhere to pure PEO, but they attach to silicate containing nanocomposites. Under aqu...

In this work the synthesis of polyaniline/chitosan/functionalized single- walled carbon nanotube nanocomposite is carried out. For this purpose single -walled carbon nanotubes were reacted with thionyl chloride to change the hydroxyl to acyl chloride groups for improving the react ability. In other step, aniline monomers and chitosan were polymerized in the presence of Iron (III) chloride to sy...

Potentiometric sensing and electrochemical recycling of cadmium ion have been demonstrated over chemical interactive electrically conducting bio nanocomposite film comprised zinc oxide, sodium alginate, polypyrrole (ZnO/SA-g-PPy) using...

The structures and mechanical properties of both physically and covalently cross-linked nanocomposite hydrogels made from poly(ethylene glycol) (PEG) and silicate nanoparticles (Laponite RD) are investigated. Injectable nanocomposite precursor solutions can be covalently cross-linked via photopolymerization. The resulting hydrogels are transparent and have interconnected pores, high elongation ...
