The emergence and advancement of cardiac tissue engineering have opened new avenues and have demonstrated promising results in practical applications. Among various biomaterials, elastic and conductive hydrogels (ECHs) have attracted extensive attention due to their excellent biocompatibility, tunable elasticity, and the potential for electrical integration with human myocardium.

We then determine the expansion coefficients that yield the number concentration as a function of particle size via mathematical optimization.
