Toward a Synthetically Regenerative World
Everyone is familiar with the experi-ence of dropping their phone—the all-too-relatable moment of fear that one will pick it up to find a spiderweb of cracks across the screen. We fear seeing our own possessions broken, whether that be through careless accidents or deterioration over time. This process of deterioration is intrinsic to many other man-made objects, ranging from the parts holding together a car or the internal metal beams bolstering bridges and skyscrapers. At some point, these structures will inevitably require replacement and maintenance. Although traditional engineering has worked to lengthen the life of such materials, biology offers new ideas for further improving their properties, one of which is the biological process of self-healing.
