A method of making an article 2 comprising an ultra-thin sheet 26 of material secured at lateral regions to a support member, the method comprises laying the ultra-thin sheet on a substrate 20 , forming the support member on the lateral regions of the ultra-thin sheet such that the lateral regions of the ultra-thin sheet are sandwiched between the support member and the substrate and adhered to the support member, and removing the substrate by vaporisation or by a dissolution step using a solvent, to leave the article. The ultra-thin sheet is supported around its periphery and has a central region in which the ultra-thin sheet is free from contact with any other material. |
