Fig. 4: FL images of the PDA particle in the mechano-FL sensor system.

From: A single-particle mechanofluorescent sensor

Fig. 4

a–d Representative FL images illustrating the variation in PDA particle FL emission upon injecting different types of solutions: pure water (a), 20 wt.% glycerin (b), 16.95 wt.% SNPs (c), 1.54 × 105 μL‒1 red blood cells (RBCs) (d), 4.80 × 104 μL‒1 yeast (e), and 2.40 × 104 μL‒1 yeast (f), corresponding to the results depicted in Fig. 3h. The images were captured at an injection rate of 25 mL·min–1 and a suction rate of 5 mL·min–1, with the flow injection time varied.
