Abstract: The present disclosure relates to oromucosal nanofiber carriers that are mucoadhesive or comprise a mucoadhesive agent for administration of active agents, including substances for their preparation, methods of preparation, and methods of use.

Abstract: Wound dressing assemblies and methods of producing the wound dressing assemblies. The wound dressing assemblies various comprise individual layers of nanomaterials that have been formed according to an electrospinning process. Each of the layers can have different characteristics and qualities. The invention also provides guidance in selecting materials to form a wound dressing assembly, as well as possible adaptations to the electrospinning process to provide different characteristics for particular materials.

Abstract: The invention relates to the method for production of nanofibres through electrostatic spinning of polymer matrices prepared upon biopolymers of chitosan or collagen. The biopolymer before spinning is dissolved as clean or in mixture with auxiliary non-toxic polymer in solvent system, which comprises an organic or inorganic acid, selected from the group of acetic acid in concentration from 30% to 90% of weight, lactic acid, malic acid, trihydrogen-phosphoric acid and their mixtures, and this solution is brought into electrostatic field between the spinning electrode and collecting electrode, while the produced biopolymer nanofibres comprise more than 90% of weight of biopolymer in dry mass.
