Figure Lengend Snippet: (A) Overlaid lactate responses plot of lactate sensors (N=3) from slabs showing linear response to lactate challenges up to 20 mg/dL of exposure. Two-way ANOVA indicated no significant differences between mean lifetimes of any given gel upto 5 mg/dL lactate concentration. However, significant differences were observed between Alginate vs. KCa, GelMA vs. KCa, and PEGDA vs. KCa gels at 10 mg/dL; Alginate vs. GelMA/KCa, GelMA vs. PEGDA/KCa at 15 mg/dL; Alginate vs. PEGDA/KCa, and GelMA vs. PEGDA/KCa at 20 mg/dL of lactate concentration, respectively. (* = p < 0.05, ** = p < 0.005, *** = p < 0.0005, **** = p < 0.0001) (B) Overlaid Stern-Volmer plots from lactate sensors (N=4) fabricated from gel slabs in different matrices.
