Ultrasonication of chitosan and chitosan nanoparticles

International Journal of Pharmaceutics, 2003
The objective of this study was to evaluate the effects of ultrasonication on chitosan molecules and nanoparticles. Molecular weight (M(v)) of chitosan HCl (M(v) 146 kDa and degree of deacetylation (DD) 96%) decreased linearly with increasing duration and amplitude of ultrasonication. DD and FTIR absorption were unaffected.

Chitosan-based nanoparticles against bacterial infections

Carbohydrate Polymers, 2021
Chitosan nanomaterials have become a hot topic in biomedicine due to exerting antimicrobial effects with interestingly high levels of biodegradability and biocompatibility without causing toxicity. Regarded as a potential means of wound dressing with antimicrobial activity, chitosan exhibits higher efficiency when it is functionally modified with other

Nanoparticles from Chitosan

Macromolecular Symposia, 2005
AbstractNovel biodegradable nanoparticles were synthesized by chemical modification of the chitosan linear chain. A natural dicarboxylic acid (malic acid) was used as a crosslinking agent for intramolecular covalent condensation reaction to obtain hydrophilic nanoparticles based on chitosan.

Chitosan nanoparticles as adenosine carriers

Journal of Microencapsulation, 2015
The objective of this research project was to evaluate the potential use of chitosan (CS) nanoparticles (NPs) as a drug delivery system for the molecule adenosine. Adenosine is an essential drug used for treating several health issues especially irregular heart rhythm. However, due to its extremely short half-life in vivo (

Platelet Compatibility of PLGA, Chitosan and PLGA–Chitosan Nanoparticles

Nanomedicine, 2009
The increasing interest in biodegradable nanoparticles containing biomaterials such as poly(D,L-lactide-co-glycolide) (PLGA) and chitosan for drug delivery raises issues regarding the blood compatibility of these nanoparticles, since some nanoparticles, including carbon nanoparticles, can affect human platelet aggregation and cause vascular thrombosis.
