Insulin-like growth factor-1 (IGF-1) is a hormone comprising seventy amino acids that is a key regulator of muscle and bone health and is highly related to the development of cancer. An aptamer-antibody sandwich assay was performed to determine the presence of IGF1 on a gold nanoparticle-enhanced di...
