Chitosan nanoparticles act as an adjuvant to promote both Th1 and Th2 immune responses induced by ovalbumin in mice.

The study was conducted to investigate the promoted immune response to ovalbumin in mice by chitosan nanoparticles (CNP) and its toxicity. CNP did not cause any mortality or side effects when mice were administered subcutaneously twice with a dose of 1.5 mg at 7-day intervals.

Preparation, characterization and antibacterial properties against E. coli K(88) of chitosan nanoparticle loaded copper ions.

The present study was conducted to prepare and characterize chitosan nanoparticle loaded copper ions, and evaluate their antibacterial activity. Chitosan nanoparticles were prepared based on ionotropic gelation, and then the copper ions were loaded. The particle size, zeta potential and morphology were determined.

Preparation, characterization and adsorption properties of chitosan nanoparticles for eosin Y as a model anionic dye.

The present study dealt with the adsorption of eosin Y, as a model anionic dye, from aqueous solution using chitosan nanoparticles prepared by the ionic gelation between chitosan and tripolyphosphate. The nanoparticles were characterized by atomic force microscopy (AFM), size and zeta potential analysis. A batch system was applied to study the adsorption of eosin Y from aqueous solution by chitosan nanoparticles.

Improvement of the thermostability and catalytic activity of a mesophilic family 11 xylanase by N-terminus replacement.

To improve the thermostability and catalytic activity of Aspergillus niger xylanase A (AnxA), its N-terminus was substituted with the corresponding region of Thermomonospora fusca xylanase A (TfxA). The constructed hybrid xylanase, named ATx, was overexpressed in Pichia pastoris and secreted into the medium. After 96-h 0.
