Aplicação

  • Chitosan has in the last decades been widely used in a variety of applications, both industrially and pharmaceutically.
  • Its positive charges under slightly acidic conditions allow it to form complexes or nanoparticles.
  • During the delivery process, the stable compact structure of the complex, with cationic chitosan chains as the outershell and the anionic genes/drugs as the core, efficiently protects genes/drugs from the ″sweeping effect″ of mucociliary clearance and degradation by enzymes.

Peggy Chan et al.
Biomaterials, 28(3), 540-549 (2006-09-27)
Poor water solubility and low transfection efficiency of chitosan are major drawbacks for its use as a gene delivery carrier. PEGylation can increase its solubility, and folate conjugation may improve gene transfection efficiency due to promoted uptake of folate receptor-bearing
Li Xiang et al.
Physical chemistry chemical physics : PCCP, 21(37), 20571-20581 (2019-08-01)
PEGylation can modify the physicochemical properties of native chitosan and improves its water solubility. PEGylated chitosan has been widely used as a gene/drug delivery vector by forming a polyelectrolyte complex (PEC) in biomedical engineering. The molecular interactions of PEGylated chitosan
