Peptides and proteins are substance of fundamental importance for all life. These molecules consist of amino acids assembled in chains and can be produced by artificial means by building the chain in steps. At the beginning of the 1960s, Bruce Merrifield developed a method for avoiding significant impurities in the final product that result from a relatively small amount of impurities in each step. If a chain-formed molecule in solid form is attached to the first amino acid, impurities can be rinsed away between every step. This process can be carried out mechanically.
