"Chemists Break Record with 54-Atom Tightest Knot"
Chemists have set a new Guinness World Record for creating the smallest and tightest knot known to date, composed of 54 atoms and made of gold, carbon, and phosphorus. The knot, a continuous loop in a trefoil shape, surpasses the previous record with a remarkably low backbone crossing ratio (BCR) of 18. This achievement pushes the boundaries of knot length at the molecular scale and showcases advancements in self-assembled "metallaknot" research.
