Biomimetic replica of the surface of micropapillae on the epidermis of a rose petal

SEM images of an epoxy replica of the epidermis of a rose petal showing replicated papilla (scale bar = 10 μm). The replica was obtained by a two-step moulding process. A first negative mould is obtained using a polyvinylsiloxane polymer and then a positive replica is created with an adequate epoxy resin.
