Description
Hanna G Goldberg and colleagues tested in 2026 short peptoid coatings for keeping gold nanospheres evenly dispersed in water. Peptoids are sturdy cousins of peptides that are easy to make and gentle on living tissue. Their library covered five-residue peptoids wrapped around gold spheres ten nanometers wide.
Certain sequences kept the spheres dispersed across wide ranges of salt content and acidity. The team measured coated sphere sizes and surface charges and compared them with peptide-coated counterparts. One peptoid coating did extra duty: spheres wearing it inhibited chymotrypsin, a digestive enzyme. Such side functions matter because coatings can reshape how proteins behave at particle surfaces. The authors map which sequence features buy stability, guiding designers who need reliable gold colloids for sensing or medicine.
