Drug loading, release kinetics, and mechanical characterization of DEX-loaded microPlates (DEX-μPLs). (a) DEX-μPL fabrication yield and drug loading characterization; (b) DEX release profile from μPLs under the sink condition (4 L, red line) and Weibull function fitting (red line; 95% confidence band); (c) DEX release profile from μPLs under confined conditions (500 μL; green line; 95% confident band) and Weibull function fitting; (d) force-displacement curve for a flat punch indentation experiment on μPLs (average curve and standard deviation). In the inset, a schematic of the experimental setup is provided; (e) mechanical damping of μPLs upon cyclic loading (frequency 5 Hz) as a function of the force oscillation amplitude. In the inset, a schematic of the testing routine highlights the phase angle δ—dissipation parameter. Results are presented as the average ± standard deviation (SD) (n = 3).
