Peptide design is not for the faint-hearted. It requires an arsenal of techniques, from the cunning use of peptide mimics that can sneak past the body’s defenses, to the wizardry of peptide stapling, which locks peptides into their bioactive shapes. Let’s not forget the emerging trend of using cell-penetrating peptides to deliver therapeutic payloads directly into cells. Each technique is a piece of the puzzle, fitting together to create peptides capable of tackling some of the most challenging diseases.
