Three-dimensional printed protein-based robotic structures are actuated by exoskeleton-like coats of molecular motor assemblies upon the spatially targeted release of chemical fuel, resulting in micrometre-scale shape-morphing activity.
This Perspective reviews the complementary developments in synthetic biology and biomaterials and discusses how convergence of these two fields creates a promising design strategy for the fabrication of tailored living materials for medicine and biotechnology.
A symbiotic culture of bacteria and yeast is used to fabricate bacterial cellulose-based living materials that respond to external cues and adapt their structural and functional properties, with implications for sensing and catalytic applications.
An approach to form protein-based hydrogels in living cells that resemble physiological hydrogel-like size-dependent molecular sieves is presented. Synthetic RNA granules mimics are obtained by functionalizing these entities with RNA-binding motifs.
Droplets with magnetite membranes are designed to engulf in a phagocytosis-inspired manner smaller colloidal objects, demonstrating a route for sequential cargo delivery and release followed by internalized reactions.
This Review discusses the materials and electronic requirements for flexible sensors and electronic systems to mimic the mechanical and sensing properties of natural skin, with the goal of providing artificial prostheses with sensing capabilities.
