What Do Spiders Have in Common with Batteries?

Spider silk inspires new class of functional synthetic polymers: Conducting protein-based material could be used in fuel cells, batteries or act as sensor

14-Aug-2020

Synthetic polymers have changed the world around us, and it would be hard to imagine a world without them. However, they do have their problems. It is for instance hard from a synthetic point of view to precisely control their molecular structure. This makes it harder to finely tune some of their ...

Well shielded but highly active

Architecture is key: Biomolecule metal–organic hybrids with high bioactivity

03-Jul-2020

Biomacromolecules incorporated into tailored metal–organic frameworks using peptide modulators are well shielded but highly active thanks to carefully tuned nanoarchitecture. As scientists report in the journal Angewandte Chemie, this strategy can be used to synthesize an “artificial cell” that ...
