About this collection
Proteins are privileged macromolecules that play critical roles in catalysis, extracellular matrix structure, cargo transport, and cell signalling. Over the past two decades, the role of peptides as functional components of materials systems has been elucidated. These systems have found use in a variety of emerging technologies spanning optoelectronics, energy conversion, regenerative medicine and drug delivery.
In this collection, guest edited by Professors John D. Tovar, Honggang Cui and Dave Adams, we focus on some of the latest exciting research where peptides and peptide mimics are treated not as isolated molecules of therapeutic value but as components of larger collective systems.
New articles will be added to this collection as they are published.
