The materiality exhibited by humanmade polymers currently relies on simple chemical bonds and the sequence order taken by molecules in the polymer chain. We now no longer need to rely on fate to determine such materiality with this new technique for precisely defining polymer-chain order. This system uses highly specific ‘grabber’ ends on each molecule that bond with only one type of 'pin’ end on another molecule.
