Figure 1

Injectable phosphorescence biosensor overview. (a) Small size (5 mm × 0.5 mm) allows local tissue measurements and injection by an 18 gauge needle. (b) Excitation light from reader reaches biosensor. (c) Sensor phosphorescence changes depending on oxygen concentration. Illustrated by Lauren Halligan, MSMI; copyright Duke University; with permission under a CC-BY 4.0 license.
