Description
Arkadios Marathianos and ten co-authors image single polymer chains at near-atomic sharpness and weigh them by counting their heavy atoms. Their paper appeared in two thousand twenty-four. Knowing a polymer's molecular weight precisely is basic to designing it. Yet seeing one chain clearly enough to count its parts was out of reach.
The trick is to build chains with metal-rich side groups that shine in an electron microscope. Dark-field scanning images then reveal each heavy atom along the chain. Counting atoms gives the weight directly, even at very low sample amounts. A common plain polymer was chemically tagged to join the club. That extends the method toward everyday plastics. The work opens polymer analysis at the level of single molecules.
