Since peptide synthesis was first established in the 1950s, techniques have continued to evolve, leading to the development of peptides capable of application in a wide range of manufacturing settings, including the development of various materials and products, as well as drug discovery. The diverse variety of items that can be manufactured thanks to peptide synthesis includes gold (Au) nanoparticles synthesized with the aid of peptides for use in photothermal therapy, which involves heating cancer cells to a specific temperature to kill them, and also cell culture interfaces used in regenerative medicine, and sensors to detect viruses and explosives.
