Biological microstructures continuously change and adapt to their environment. They develop and evolve through a series of reactions termed morphogenesis. In contrast, synthetic microstructures are static and usually do not respond to their environment. The dynamic nature of biological microstructure teaches us about nature’s ability to solve problems, an ability that we can find very useful in synthetic materials.
In this talk, I will present a new approach for mimicking natural microstructures. Instead of mimicking the microstructure itself, I will present a method for mimicking the process that led to the formation of that microstructure. Using a microvascular flowing system and biological development as inspiration I will show how a simple depolymerization and inhibition of that depolymerization, a reaction-diffusion process, leads to improvement and adaptation of the structures. I will furthermore present the next steps in which both polymerization and depolymerization occur in the same system. This leads to a dynamic formation and removal of material in the microstructure that is completely dependent upon the balance of the chemical equilibrium.
