The influence of natural rubber/Au nanoparticle membranes on the physiology of Leishmania brasiliensis

► Studies on interaction of promastigotes and natural rubber with gold nanoparticles. ► Natural rubber membranes containing GNPs decreased the population growth rate. ► Future development of a flexible band-aid for skin lesions. ► Inhibiting the population growth of Leishmania brasiliensis parasites.
