Molecular Lego of knots

10 marzo 2015

Trefoil, Savoy, or simple … how do you fashion a «molecular» knot that has one of these shapes? Or better still, what are the most suitable «building blocks» for enabling the knot to assemble itself? A team of scientists has studied and catalogued the shapes that molecular building blocks should have so as to be able to assemble spontaneously into knots having specific forms, each with a possible utility in nanotechnology.
