Photosynthesis-assisted remodeling of three-dimensional printed structures

Abstract

Living creatures are continuous sources of inspiration for designing engineering materials and structures. However, synthetic engineering materials are typically different from living creatures, because the latter consist of living cells to support their metabolisms, such as remodeling, growth, and reproduction. How to harness living cells to metabolize synthetic engineering materials remains largely elusive. Here, we report an attempt to exploit living chloroplasts to metabolize three-dimensional-printed polymers. With living chloroplasts and synthetic polymers, the system leads to a class of hybrid synthetic-living materials whose microstructures and properties can be remodeled on-demand by the photosynthesis of chloroplasts.
