Abstract
Lyotropic liquid crystalline systems are of great interest as carriers of biological substances for targeted delivery, mainly for transdermal administration of drugs and their application to the skin and mucous membranes. The wetting and adhesive interactions of lyomesophases and gel based on a chitosan polysaccharide in lactic acid solution on a glass substrate (base surface) and the surface of a semi-permeable polytetrafluoroethylene membrane (model of epidermis horny layer) were studied. The effect of the riboflavin drug (vitamin B2) on the surface tension of studied samples and the amount of adhesion work has been established. It is shown that biocompatible chitosan-containing systems can be used as drug carriers for various biomedical purposes, including transdermal drug delivery.
