This study sheds light in the mechanism of interaction between antibodies and PEG-coated drugs. The insights provided by this work will help the development of better ‘stealth’ polymers and more ...

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 ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily. So for ...
