Glycine detection with a nuclease-stable L-RNA sensor

Glycine is a vital extracellular signal in bacteria, plants, and the brain. Although RNA-based sensors detect glycine in cells, their extracellular application in native biological environments is limited by enzymatic degradation from nucleases. Mirror-image RNA is nuclease-resistant and preserves the tertiary structure required for RNA function, but synthesizing long L-RNAs such as the 170-nt…
