Fluorescent polymer conjugate was stable throughout the anticipated use case. (A) Representative fluorescent images of devices after exposure to simulated gastric fluid (SGF) and simulated intestinal fluid adjusted to pH 5 (SIF). (B) Comparison of maximum pixel intensity between fluorescently labeled devices exposed to SGF for 30 min, SIF adjusted to pH 5 for 60 min or 4 h. Data represents mean ±1 SD of n = 5 devices per group. No differences were detected between groups at α = 0.05, using a one-way ANOVA followed by a Tukey-Kramer correction for multiple comparisons.
