Synthetic multivalency for biological applications

Current directions and emerging possibilities under investigation for the integration of synthetic and semi-synthetic multivalent architectures with biology are discussed. Attention is focussed around multivalent interactions, their fundamental role in biology, and approaches in emulating them in terms of structure and functionality using synthetic architectures.

About this collection

The understanding and control of multivalent biomolecular interactions has become one of the key frontiers of chemistry and biology. This themed collection highlights some of the important findings and advances in the field, in order to:

  • Develop functional sugar decorated nanoplatforms (nanoparticles, nanostructured surfaces, vesicles, microarrays, etc.).
  • Understand the biomolecular mechanisms by exploring their synergistic adaptive interactions with biomolecules, in order to accurately control the chemical/biological responses.

The collection is Guest Edited by Professors Mihail Barboiu (Institut Européen des Membranes, France), Olof Ramström (KTH - Royal Institute of Technology, Sweden) and Stéphane Vincent (University of Namur, Belgium). New articles will be added to this collection as they are published.
