Improving peptide quantification in chitosan nanoparticles

International Journal of Biological Macromolecules, 2018
Abstract The objective of the present study was to evaluate different methodologies for peptide quantification in the supernatant of chitosan nanoparticles by removing the unliked polymer in the suspension. The ionic gelation method was used to prepare the chitosan nanoparticles encapsulating a 5.3 kDa peptide.

Chemical Binding of Chitosan and Chitosan Nanoparticles onto Oxidized Cellulose [PDF]

Journal of Engineered Fibers and Fabrics, 2015
The aim of this study was to analyze binding of chitosan and chitosan nanoparticles onto cellulose via oxidized cellulose. The ability of chitosan and chitosan nanoparticles to be adsorbed onto surfaces was determined by the use of the XPS spectroscopy which provided information about chemical composition of the fiber surface.
