The polymer, called polyethylene glycol or PEG, works by "fusing" the membranes of damaged nerve cells, and it can be applied up to eight hours after the injury without adversely affecting the patient ...

Imagine a microscopic locomotive moving back and forth along a track, propelling itself without any external force. At the molecular level, this concept forms the foundation of molecular motors -- ...

PEG-Naloxol (NKTR-118) in Phase II clinical trials. Clinical benefit has already been demonstrated with polymer–drug conjugates bearing classical chemotherapeutic agents. The future of cancer ...

Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...
