We have developed an efficient strategy for the non-covalent functionalization of multi-wall carbon nanotubes (MWCNTs) which allows a biomimetic presentation of carbohydrates on their surface by π-π stacking interactions. The strategy is based on the use of...

Autophagy is a catabolic membrane-trafficking process whereby cells recycle cytosolic proteins and organelles under stress conditions or during development. This degradative process is mediated by autophagy-related (ATG) proteins which have been described in yeasts,...
