About this collection
A collection of original research and reviews focussing on Biomaterials for Imaging and Sensing. The goal of this collection is to highlight the most exciting advances in responsive materials, as applied to real-time analysis of analytes relevant to life sciences including proteins, electrolytes and cells. Both in vivo and in vitro measurements were welcome. Here, we define biomaterials broadly including any number of soft or hard materials including plasmonic materials, polymeric systems, self-condensing approaches, biomimicry etc.
