Proteins and peptides are widely used in various areas including pharmaceutical, health, food, textile and biofuel industries. At present, pharmaceutical proteins and peptides have attracted the attention of many researchers. These types of drugs are superior to chemical drugs in many ways so that every year the number of drugs with a protein or peptide moiety is increasing. Due to high performance and low side effects, the demand for these drugs has increased year by year. The beginning of the protein and peptide drug industry dates back to 1982 with the introduction of the protein hormone insulin into the field of treatment. From this year onwards, a new number of protein and peptide drugs have entered the field of treatment every year. In this article, we focus on human therapeutic insulin. First, the history of the hormone will be introduced, then-current methods for insulin therapy will be discussed and finally, the treatments by this hormone in the future will be pointed. Reading this article would be very helpful for nano researchers, biochemists, organic chemists, material scientists and other people who are interested in soft and hard matters interfaces.
