The carbon-on-gold substrates used in this work consist of a lamellar structure (a) in which an SPR conducting gold thin film was evaporated onto a high-index glass substrate and then an amorphous carbon overlayer was sputtered onto the gold. The amorphous carbon was then hydrogen terminated in a 13.65 MHz inductively coupled hydrogen plasma and UV photofunctionalized with 9-decene-1-ol to yield (b) a hydroxyl-terminated surface. An (c) oligonucleotide array was then synthesized on the substrate in a base-by-base fashion using photolithographic chemical methods.
