I desire the former record - holders are n’t too cross : a squad of researchers recently made the small-scale , tightest knot yet known , shoot down themselves top spot in the Guinness Book of World Records .
The knot is compose of 54 atoms , chained together and ensnared in a trefoil , thesimplest nontrivial gnarl . The knot has no light end ; it is a uninterrupted iteration , passing through itself in mesmerizing arcs . The squad ’s work name the self - forgather “ metallaknot ” waspublishedin Nature Communications .
It is made up of amber , carbon , and phosphorus , asreported by New Scientist . The knot is formulaically described as [ Au6{1,2 - C6H4(OCH2CC)2}3{Ph2P(CH2)4PPh2}3 ] , or Au6 for short , in reference to the six Au speck in the burl .

You may wonder how a team settle the niggardliness of a knot at the molecular scale . As the researchers state in their paper , the knots are “ classify according to the minimum number of crosswalk when the tighten form of the social organization is projected onto a two - dimensional surface . ”
In 2017 , a squad of researcher craft a knot with 24 particle per crossover , whichmade it into the Guinness Book . In 2020 , a unlike teammanaged to producea 69 - atom - foresighted knot with a backbone crossbreeding ratio ( or BCR ) of 23 , making it the record bearer . The smaller the BCR , the tighter the mile .
The newest — and indeed , smallest and tight knot — get the 2020 record . The new mi is just 54 atoms long , and has a unmistakably low BCR of just 18 . It is slopped than the BCR of the tightest organic trefoil burl by a BCR margin of 7.3 .
consort to ScienceAlert , the mi is butt on closely to the theoretic point of accumulation of knot distance . Previous research suggestedthat the smallest clover knot ought to control “ at least 50 ” atoms .
The late accomplishment is slub — er , not — the only gnarl to nurse a place in the Guinness Book . Thelargest human knotwas made in 2019 and involved 123 people . Thelargest Chinese knotwas made by a kindergarten class and was over 130 foot marvellous and 136 feet across , according to the book of account . The pantheon of notable greyback is obviously a large one , but surely the new record can not be beaten … or can it ?
