Polysaccharide films modified by compounds of natural origin and silver having potential medical applications

Abstract In the first stage, seven polysaccharide films were prepared with varying compositions of starch, carboxymethyl starch (CMS), and cellulose (CMC), together glycerol citric acid. From these samples, most suitable film for possible future applications in medicine form patches was selected based on tensile strength tests, solubility water, moisture sorption, swelling, wetting angle. This (labelled as “V”) contained (in wt%) CMS (2.5), CMC acid (3), (3). second used further by individually introducing into it appropriate additives known antimicrobial activity. These consisted terpene compounds natural origin (α-pinene, menthol, eugenol) well colloidal silver. four then studied to determine influence additive absorption, The results microbiological tests confirmed activities, also anti-infective regenerative effect films. general, containing terpenes showed comparable or better medicinal properties than obtained A patch prototype (with a medical net) optimal (“V”) developed, its flexibility is apparent that can take shape size area human body should cover.
