Shedding light on bacterial fitness in a tug-of-war with liquid crystal emulsions
Abstract Rapid and reliable quantification of bacterial dynamics at the cellular level is critical for pathogen sensing, live-dead bacterial assays, and monitoring of bacteria fitness and viability. Here, we demonstrate bacterial fitness quantification by capturing individual cells on topological defects of micro-scale liquid crystal emulsion droplets.
Scalable optical manufacture of dynamic structural colour in stretchable materials - Nature Materials
Abstract Structurally coloured materials that change their colour in response to mechanical stimuli are uniquely suited for optical sensing and visual communication1,2,3,4. The main barrier to their widespread adoption is a lack of manufacturing techniques that offer spatial control of the materials’ nanoscale structures across macroscale areas.
Luminescent surfaces with tailored angular emission for compact dark-field imaging devices
Abstract Dark-field microscopy is a standard imaging technique widely employed in biology that provides high image contrast for a broad range of unstained specimens1. Unlike bright-field microscopy, it accentuates high spatial frequencies and can therefore be used to emphasize and resolve small features.

Multifunctionality of chiton biomineralized armor with an integrated visual system
Although many biological tissues serve more than one purpose, rarely are they optimized to do multiple tasks well. When you try to optimize for one functionality, it comes at the expense of another. Li et al. investigated the biomineralized armor of the small mollusc chiton Acanthopleura granulata. The armor appears to be optimized for both mechanical strength and for image capture by hundreds of integral aragonite-based lenses.
