Chitosan-derived Polymer-surfactants and Their Micellar Properties

Effectiveness test of alginate‐derived polymeric surfactants

“…2,19 Azobenzene is almost insoluble in water, 9.04 Â 10 À6 mol dm À3 , but can be soluble in the hydrocarbon core of anionic surfactant micelles. The solubilization measurements were carried out as follows.…”

Spin Probe Study on the Interaction of Chitosan-Derived Polymer Surfactants with Lipid Membrane

“…The method for the synthesis of S-Cn-Chitosan was described in the previous paper (5). In this experiment, three S-Cn-Chitosan possessing different acyl chains were used, namely, sulfated-caproyl (C6)-, decanoyl (C10)-, and myristoyl (C14)-chitosan.…”

“…We have been trying to synthesize nontoxic and biodegradable polymer surfactants from naturally occurring polymers (3)(4)(5) for use in medicines and foods. Chitin is a polysaccharide obtainable in large amounts from the shells of Crustacea like crabs and shrimps (6,7).…”

“…The polymers synthesized in this way (abbreviated as S-Cn-Chitosan, the structure is shown in Fig. 1 along with those of chitin and chitosan) were water-soluble and formed a polymer micelle which was able to dissolve hydrophobic substances like azobenzene, if alkyl chains were longer than C8 (5).…”

Quitosana: biopolímero funcional com potencial industrial biomédico

“…78 Matriz de N-lauril carboximetilquitosana contendo grupos hidrofóbicos e hidrofílicos foi estudada na liberação de taxol para tratamento de tecidos cancerosos. 79 Outros exemplos são relacionados à produção de vesículas poliméricas para encapsulação de compostos hidrofóbicos como bleomicina. 80 Na literatura, é bastante reportado que a velocidade de liberação de fármacos a partir de matrizes de quitosana é afetada pela mudança do pH.…”
