Entangling strands in a well-ordered manner can produce useful effects, from shoelaces and
fishing nets to brown paper packages tied up with strings. At the nanoscale, non-crystalline …

Molecular nanotopology—a term we coined recently—is a rapidly developing field of
research that is emerging out of the confluence of chemical topology with the mechanical …

The field of mechanically interlocked molecules (MIMs) has advanced rapidly in recent
years, with much work focused on their use in materials, sensing, and catalysis. However …

Nanoscale imine-linked covalent organic frameworks (nCOFs) were first loaded with the
anticancer drug Doxorubicin (Dox), coated with magnetic iron oxide nanoparticles (γ-Fe2O3 …

Current strategies for the synthesis of molecular knots focus on twisting, folding and/or
threading molecular building blocks. Here we report that Zn (ii) or Fe (ii) ions can be used to …

Molecular knots are often prepared using metal helicates to cross the strands. We found that
coordinatively mismatching oligodentate ligands and metal ions provides a more effective …

While the majority of knots are made from the metal-template approach, the use of
entangled, constrained knotted loops to modulate the coordination of the metal ions remains …

Artificial molecular machines (AMMs) have profoundly enhanced scientists' capability to
manipulate the relative movements of components within molecules. Mechanically …

From being an aesthetic molecular object to a building block for the construction of
molecular machines, catenanes and related mechanically interlocked molecules (MIMs) …

Silk fibroin (SF) is a natural protein largely used in the textile industry but also in
biomedicine, catalysis, and other materials applications. SF is biocompatible …
