Interaction between polymer capsules with hydrophobic cores and a model cellular membrane at an air–water interface

Аннотация

Submicrocapsules have been prepared from diethylaminoethyl dextran and xanthan gum on oil cores by ultrasonic treatment. These capsules have been modified with poly-L-lysine via electrostatic adsorption. The behavior of the capsules has been investigated at an air–water interface after their introduction into the aqueous subphase. The interaction of the capsules with a 1,2-dimyristoyl-sn-glycero-3-phosphocholine monolayer formed on the water surface (model cellular membrane) has been studied both upon their introduction under the condensed monolayer and with the use of a dilute colloidal solution of the capsules as a subphase.
