Biotechnologists from Siberian Federal University have created medicinal films made from a biodegradable biopolymer that includes antimicrobial and regenerative agents. These films are produced from special biopolymers obtained through bacteria and have high compatibility with the human body. They are hypoallergenic and can gradually release medicines, promoting effective wound healing, according to the university’s press service. According to the researchers, these films can be used both in medical institutions and at home, in the form of regular patches of various formats. The films are elastic and stretchable, adapting well to the skin and can be applied to mobile parts of the body, such as elbows and knees. They can be used as dressings or patches for treating both infected and regular wounds. They do not cause allergies and slowly release antibacterial and regenerative substances, facilitating effective treatment. The films contain active medications that are gradually released and penetrate the skin and muscle tissue. Research shows that the films allow air to pass through and prevent the accumulation of wound fluid, creating optimal conditions for healing and preventing scarring. The films can be produced in varying thicknesses – from 20 micrometers to larger sizes, depending on treatment needs. They do not have an adhesive base and can be fixed with existing self-adhesive dressings. These films are environmentally safe and biodegrade in natural conditions without causing harm to the environment. The research was conducted on cell cultures without the use of laboratory animals.
