Enhancement ratio of lipopolysaccharide (LPS)-treated inflamed ankles in NIR2-folate (n = 12) and NIR2-free dye (n = 5) injection groups at different time points. A significantly higher enhancement ratio was noted in the NIR2-folate injection group at 24-hour, 48-hour and 72-hour time points (P < 0.05).
