In vivo retention of CS-PF hydrogels: (A) NIR fluorescence imaging of joint of mice taken at different times after intraarticular injection with PBS + NIR 780, CS1-PF25 + NIR 780, and CS1-PF25-TPP + NIR 780. (B) In vivo retention over time of the various CS-PF hydrogels formulations indicated by relative fluorescence intensity. (C) Graphic of area under the curve (AUC) of the three studied groups. Data are presented as mean ± SD. Statistical significance was determined by two-way ANOVA with multiple comparisons; *p < 0.05, ** p < 0.01, *** p < 0.001, and **** p < 0.0001.
