This study compares calcium fluoride and stainless steel substrates for Raman spectroscopy in diagnosing colonic disease, finding that optimized calcium fluoride matches stainless steel performance but at lower cost.

The paper constructs acetoacetate-sensitive whole-cell biosensors using the AtoSC two-component system and demonstrates their functionality in E. coli.

The paper develops a bacterial biosensor system in C. elegans to detect environmental changes in the intestinal tract using an inducer.
