Scientists are tying the tiniest, tightest knot of just 54 people

Researchers have created the smallest, tightest knot known, securing a place in the Guinness Book of World Records, according to Gizmodo.

The knot, consisting of 54 atoms chained together in a trefoil, is a continuous loop with no loose end and is composed of gold, carbon and phosphorus. Young Scientist mentionted.

The team’s work describing the self-assembling “metallaknot” was published in the journal Nature communications.

The knot is typically described as [Au6{1,2-C6H4(OCH2CC)2}3{Ph2P(CH2)4PPh2}3]or Au6 for short, about the six gold atoms in the knot.

But how does one determine the tightness of a knot on a molecular scale?

According to the team’s paper, the nodes are “sorted according to the minimum number of intersections when the reduced form of the structure is projected onto a two-dimensional surface.”

The youngest, and indeed, the smallest and tightest knot in history, breaks the record set by a team in 2020.

The 54-member long knot has a trunk crossing ratio (BCR) of 18, a significant improvement from the previous record of 69 members with a BCR of 23.

The smaller the BCR, the tighter the knot. The new knot is tighter than the BCR of the tightest organic trefoil knots with a BCR margin of 7.3.

According ScienceAlert, the knot closes close to the theoretical limit of knot length. Previous research suggested that the smallest cloverleaf knot should contain “at least 50” individuals.

The recent achievement is not the only knot that holds a place in the Guinness Book of Records.

The largest human knot took place in 2019 and involved 123 people.

Meanwhile, the largest Chinese knot in the Guinness Book of Records was made by a kindergarten class, measuring more than 130 feet tall and 136 feet wide, according to the book.
