Aggregation of hydrophobically modified chitosan in solution and at the air–water interface

Biotinylated N-palmitoyl chitosan for design of drug loaded self-assembled nanocarriers

“…The CMC values indicated that formed micelles are more stable upon dilution than those based on other chitosan derivates (e.g. oleoyl-chitosan; CMC from 79.43 to 10 mg/mL) (Li et al, 2006). …”

Effect of oleoyl-chitosan nanoparticles as a novel antibacterial dispersion system on viability, membrane permeability and cell morphology of Escherichia coli and Staphylococcus aureus

“…OCNP were prepared according to our previous method (Li et al, 2006(Li et al, , 2007. In this study, the sample with a degree of substitution (DS) 5% of oleic acid was chosen to prepare nanoparticles for its superior antibacterial activity (Xing et al, 2008).…”

“…Some of these chitosan amphiphilic derivatives can form nanosized self-aggregation in aqueous media (Janes, Fresneau, Marazuela, Fabra, & Alonso, 2001). In our previous study (Li et al, 2006(Li et al, , 2007, oleoyl-chitosan (O-chitosan) nanoparticles (OCNP) were prepared using an O/W emulsification method based on O-chitosan, which were synthesized by grafting oleoyl onto the -NH 2 at C-2 in the chitosan molecule. Different from chitosan, nanoparticles systems of chitosan could be well distributed in aqueous solution and less affected by pH of the solution (Xing et al, 2008).…”

Amphiphilic chitosan derivatives as carrier agents for rotenone

“…This was associated with OCMCs has the lowest number of hydrophobic group as compared to DACMCs which has the highest number of hydrophobic group. This was supported by Li et al [14] who discussed that as the higher the number of hydrophobic groups grafted to a macromolecule, the greater its ability to self-aggregation in solution. Furthermore, the increase in the molecular weight of amphiphilic chitosan derivatives increases the size of self-aggregates because of the rigidity of the chitosan [5].…”
