Fig. 6.

(A) Compressive stress of POC, BPLP-0.3Gln, BPLP-0.3Gln-Mg, BPLP-0.5Gln, and BPLP-0.5Gln-Mg composites. Data are average ± SD. One-way ANOVA with Tukey’s multiple comparisons test, *P < 0.05, **P < 0.005, ***P < 0.0005, and ****P < 0.0001. n = 4. (B) Compressive stress, (C) modulus, and (D) compressive strain of composites with incorporation of various magnesium amounts. Data are average ± SD. One-way ANOVA with Tukey’s multiple comparisons test, *P < 0.05, **P < 0.005, ***P < 0.0005, and ****P < 0.0001. n = 4 to 6. (E) Modulus and (F) compressive strain of POC and BPLP composites with incorporation of various glutamine amounts. Data are average ± SD. One-way ANOVA with Tukey’s multiple comparisons test. *P < 0.05, **P < 0.005, ***P < 0.0005, and ****P < 0.0001, n = 4. (G) Modulus and (H) compressive strain of BPLP-0.5Gln with or without magnesium incorporation. Data are average ± SD. Two-tailed unpaired t test, *P < 0.05, **P < 0.005, ***P < 0.0005, and ****P < 0.0001. n = 4. (I) Degradation of POC, BPLP-0.3Gln, BPLP-0.3Gln-Mg, BPLP-0.5Gln, and BPLP-0.5Gln-Mg films in PBS over time. n = 3. (J) Excitation and emission of POC film and BPLP films with various glutamine amounts. (K) Excitation and emission of BPLP-0.3Gln film and BPLP-0.5Gln films with magnesium incorporation. (L) Emission spectra of BPLP-0.3Gln film. (M) Emission spectra of BPLP-0.3Gln-Mg film. (N) Emission spectra of BPLP-0.5Gln film. (O) Emission spectra of BPLP-0.5Gln-Mg film. (P) Ultrasound (US) image (above) and 3D photoacoustic (PA) image (below) of POC, BPLP-0.3Gln, BPLP-0.5Gln, BPLP-0.3Gln-Mg, and BPLP-0.5Gln-Mg films from left to right at 808-nm wavelength. Scale bars, 3 mm. (Q) Quantitative analysis of the 3D photoacoustic image at 808-nm wavelength. a.u., arbitrary unit.
