Abstract: A method for producing a surface-functionalised object involves: (i) providing negative mould (2) with a surface topography complementary to that desired on the object; (ii) applying a functional entity (20) to the mould surface, in an exciting medium; (iii) forming the object (21) in or on the mould (2), the object being in direct contact, as it forms, with the functional entity (20); and (iv) releasing the object (21) from the mould, wherein during steps (iii) and/or (iv), at least some (22) of the functional entity (20) is transferred from the mould to the object, whilst a proportion remains on the mould (2) surface. The method can be used to functionalise the surface of an object as it is cast, and the mould can be re-used to form multiple replicate objects. The invention also provides an object produced using the method, and a surface-functionalised negative mould for use in the method.
